It's really annoying that the addon's name uses square brackets, pushing it to the top of the alphabetical order and separating it from other TST addons.

great add-on to quickly find last used tabs

very useful addon. But one annoying bug - sometimes when open new tab(from existing tabs / not from existing tabs) its just lost opacity order. after shifting between two tabs its get back opacity order again. fix this bug please!

Seriously degrades the performance of TST if you have a lot of tabs open. Needs some performance optimization; seems to process the whole tab list at each update instead of doing incremental or background work.
