This is SOOOO CLOSE to what I've been looking for. And that is to have categorised windows. For example 'social media', 'development', 'devops', 'home', .... and to get any new window that opens to land in the correct one of these. Currently the allocation is manual and theoretically once setup it wouldn't be much work at all. Setup works in TMP, excepting it is NOT PERSISTED. The tabs will remain together but the newly added titles do not stay. Once Markus adds a few more features on top of the *fixed version* of this plugin we will be well on the way to utopia. At that time my 4 stars will become 5.

New Features I'd desire to see include:
1. Keyboard shortcut to enter the 'search' input (Oo I found it - Shift-CMD-M by default on Mac)
2. Auto-assignment to categoriesed windows of newly opened URL. Initially can be simply based on pattern matching or base URLs. Work up to baysian learning, or based on other people's classifications.

Other Issues

1. 26.11.20 - One month later. Tonight either TMP or FireFox or another Addon (but i've never seen this happen before installing TMP), nearly every tab from every window moved to the one window. It left 1 or 2 tabs behind in each window. Pretty annoying as I purposely organise the tabs into windows.

This is an ok organizational tool for, like, a sitting. But for some reason every time I leave and come back to my computer after a day or two the headings I've set up for each open window just disappear. I have 4 windows with multiple tabs open in each, grouped by the different things I'm using those tabs for. I want to be able to easily and quickly go to the right window for what I want to do, but I always have to start by re-naming and color coding everything because it just... loses those settings after a while. It's annoying enough that I might look for a different add-on for this eventually.

Tab Manager Plus 5.2.0 is a Special Operations tool for "multi-tabbers" like me. The "Limit Tab Per Window" feature is well worth the $25 I tried to donate. Great job, Markus!

Almost just what I'm looking for... would be neat and I guess more transparent to have actual screenshots of the sites in the overview and not just icons.
I know would take up more space but doesn't need to be detailed, just a much better hint to remember what the tab is about.
Any plans for that?

Opens new window for every new url or click! Awful! Not working right at all!

I love this Addon. I ve been using it on other Browsers and Today i have discovered that its included on Firefox as well! I like the feature of automatic scrolling and showing in the list where is the tab is open at the moment! Excellent job guys!

>>> REQUEST: PLEASE ADD FUNCTIONALITY INTO TAB AND SIDEBAR (RATHER THAN JUST MENU). <<< THANK YOU! :D :D :D :B :B :B

Easiest and most useful interface of all the tab managers I have tried.

I really want a simple extension that will let me **quickly** delete tabs I don’t need any more. There is nothing that I’ve found. This extension either needs you to search for a term or to right-click on every tab you want to close. I can predict some things that need closing but there are lots of random things on the internet and I just need a simple list, either with check-boxes or click to select (& drag to select) to quickly remove tabs. A mode where a simple click would remove a tab would be awesome.

This is just amazing!!!! Super...

Neat and easy to use!

Brilliant extension. Let this one last forever. I miss tab mix plus.

Amazing! the doctor's recipe I was looking for fix the Firefox's default unhealthy tabs "messy" BIG thanks!
Note: I just started using TMP and I know there are some flaws to fix, but at this point it DOES what it promises beyond what I ever could before.

Love it! Sidebar function needs work but awesome extension, look forward to future updates!
