Last year at this time, just about none of these tools existed.
I count 22 different tools now between the three menus, a plethora of options that are either completely unique or unique in some way - we didn't build anything that wasn't needed - these aren't pallete-swapped clones of things that already exist, though many of the tasks these tools can do absolutely can be done with other interfaces - sometimes just having a standalone version is useful enough - but most of these have at least one special or unique feature that was IMPOSSIBLE beforehand without knowing about scripting or command line.

So let's go through them one by one!
You can delegate in any front-end, but the really cool thing here is the verbose URLs you can build to make inviting users to delegate to a project that much easier with several fewer clicks.
Authorities are one of those things that fully-featured front ends do have, somewhere, usually hidden in a menu. On top of that, you can only see authorities for accounts on which you are logged in, to see anyone else's you will have to go to a block explorer, where you cannot edit them.
Our great authority manager let's anyone quickly check authorities between multiple accounts, as well as manage them immediately. A great addition to the ecosystem!
A simple to understand and easy tool to create accounts if you already know about HIVE. This might possibly be the exception of our tools having utility not found elsewhere, but since we were making some unique account creation options anyway, we have this simple and clean standalone tool on our site.

Breaking the master password into the individual keys is something that can be done with math. It is not necessary to send the key anywhere to get it broken down into components, and so we made a front-end only tool to break up the master password. As far as I know this is the only tool of its kind that exists as a standalone tool that doesn't require login and searching through menus.
I wanted this tool for so long, I was tired of claiming accounts without being able to see the price first - its dynamic after all and is frequently 3 or even 5 times as expensive as one would like to pay for "free" account tokens. We have a fun and friendly chart, track the data and allow you full control of your account claims.
Additionally, if you happen to be an edge case with a lot of RC and relatively low HP - this is the only tool that I know of that will even let you claim multiple accounts. Sure there are "automation options" out there, but I like full control.

Everyone knows that you can use the owner key to change one or more of your other keys. But keychain (rightfully) doesn't even accept the owner key, making any transaction of this type worrisome and precarious. The current tools were woefully inadequate, and raised the likelihood of catastrophic error - sometimes even above the risk of not changing your keys.
Our site is slow, actually forces you to download the keys (instead of just insisting with popups no one reads anymore), and gives users the peace of mind through what can be a scary process when you actually need it.
This is an interesting visual tool that shows all users who vote on at least 1 proposal, which is some definition of the word "active", and compares them by their total governance HP (including proxies). Can be especially useful for those trying to get their own proposal passed, or even to people who want to be accurate in their complaints about the things they don't like.
One of our most used and all-time fan favorites - the only remaining Hive-Engine market that shows which accounts are behind the various buy and sell orders on all of the individual tokens' order books. There are also filters, richlists and other interesting information available, but seeing the orders makes all the difference here.

Have you ever wondered which are the accounts making all that volume on the internal market? Or maybe wanted to see which users were the top traders on our Hive-Native HBD exchange. Then this is a cool visualizer tool for you - track internal market volume by accounts and see who is making the waves and moving the price!
Like the Delegation app, its not about what this tool does, which is allow people to send money, but through verbose URL construction, to allow users to program links that allow donations or sales with the least clicks possible (3, or 4 with an offsite warning message). So if you think all these tools are cool - Send a dollar to our development team.
This is actually a 2-in-1, very useful to decrypt memos more than a few days old; on current interfaces you have to load completely the wallet transactions back days, weeks, months or years to find and decrypt that secret message - this tool makes that a lot easier. But it also allows "off-chain" encryption and decryption using Memo Key (like encrypted memos use), posting key (like sting chat uses) or even other keys.
Key pair encryption is no joke (its cool tech!), and we have it native to HIVE accounts. This is the only standalone tool that I know of - EVER - to add functionality and ease of use to this HIVE feature.

Managing communities - including roles, permissions and titles, is something that is very possible to do on HIVE, communities are actually accounts themselves. But like many things, there is no "great" interface dedicated to this, and every attempt involves logging out and logging in multiple times with multiple accounts and navigating menus searching for the right buttons. Here is a tool dedicated to managing a community on HIVE!
How did they do that?
A long time ago in a galaxy far away, I started my journey of sharing what I had learned with Markdown Tutorial posts. If you have ever wondered how an author is managing to get an effect into their posts - the answer is that we have a special semi-limited form of markdown/html codes that we put right into the blocks and the front-ends render. And you should be able to see it (since its on blockchain), but here is the first tool to do so easily.
Copy and paste a link to any HIVE post to see the markdown, and even test and check how edits would affect them.
Another beauty here - of course I love HIVE and the fact that all my content is backed up and stored, because I love my content; a lot of it is evergreen. But what can you do with that content, besides sharing one of a dozen links that each make the post look slightly differently? Well now you can "export" any post to PDF, for offline sharing, printing or avoiding talking about cryptocurrencies.
Markdown2PDF is one of those tools that I think has never existed, but as soon as you see it you say, "Wow, that is useful!".

There are several ways to see edits, buttons hidden across different interfaces. But sometimes your mom wants to know something and you just need an easy link to send her to. A standalone special, analyze edit patches and the history of any post or comment with this tool.
A nice HSBI utility for looking up user information and pre-sanitizing sponsorship transactions, this is a quality of life tool available for the HSBI community on HIVE.
If you are one of those people that feel some responsibility to try to pay taxes to your government - this is a great tool for you. Its that time of year again, so if you are not into running your own scripts, you can use this tool to extract wallet information reports (in .csv format) for use in your own spreadsheets or reporting.
You don't even have to pay taxes, in which case this would be a tool to see how much you saved on taxes by using crypto.
As someone who has 8 years of blogs written, this is one of the tools I most wanted. I was tired of using google search to find my own blogs - or trying to back load years of posts by scrolling intermitently in order to go back in time on classic front-ends; it can be a real pain. The backlinker results are links, plus you can copy them already markdown ready, so this is great for searching for links to old posts to cross-link in your new posts.

This is my very favorite tool for filtering my own HIVE content - it uses images to make the process very visual. You can use this to find images you uploaded in old posts - possibly saving some space on our shared images.hive.blog servers (Rest in Peace). Click on any image to carousel through all the images from that post:

This really handy tool was built with community feedback through the great work of @friendlymoose - use a plethora of filters to sort and discover new and curate-able content on the HIVE blockchain. Sometimes being a better curator means using better tools.
A tool to find new posts and comments by tag - another search/filter tool to come at all the content being stored on HIVE in a unique way.
One of my favorite pages, we continue to accumulate a link-tree to not only all of our open source work, but also that of others, and include many useful links to documentation and other information for people interested in developing on HIVE.

I want to thank especially @thecrazygm for putting up with working with me for so long - make sure to check out his blog especially if you like the nerdy stuff. Throw us some motivation by telling us in the comments which is your favorite tool - and why?
Awesome stuff. I have tried a few apps and in time I will dive in a little deeper. I have to be careful not to get too far away from my priority work.
I have noticed in Hive-Engine Market Viewer that I need to refresh sometimes for a couple time before the order list is correct at the time of viewing. Is there some caching of data within the app data handling?
!PIMP

Yes, there is between a 5 and 15 minute cache of some of the data, the longer cache is for things like the token list, the markets have a 5 min cache.
Cool. What I expected and I had noticed the change because of the number of trades I execute. Had to adopt another level of awareness. !LOLZ
Have you considered a link to download a csv file of the dataset behind the chart?
