[Idea] There should be an extension to add strings to tabs name in order to create groups of tabs that this extension could then hide/show! (If anyone ever thinks of doing this please remember that firefox allows to select tabs with CTRL, which is a really nice way to get the task done.)

[Review] Thought that the command style wasn't for me, but actually is really practical.

I have way too many tabs. Being able to filter out and in tabs on the fly makes cleaning old ones out simpler. And I can make temporary tab subset "sessions". Have only used it for today but it's pretty instant to swap out your entire set of tabs and it has already helped a lot. And the tabs stay loaded/unloaded when you swap them in and out and keep their order so I haven't had any annoying experiences like so many other addons bring.
