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.
