I somewhat recently switched from Edge and had fallen in love with vertical tabs, more specifically an auto-hide favicon'd list that expands when hovered over. This addon was able to fulfill all my vertical tab desires ❤️

More details on their GitHub, if you're like me and want a thin sidebar that expands when moused over: https://github.com/piroor/treestyletab/wiki/Code-snippets-for-custom-style-rules#auto-showhide-sidebar-by-mouseover-hover

Ogólnie bardzo dobre rozszerzenie, jednak ma jedną wadę: zajmuje sporo miejsca w ui, poza tym OK

Really helps with worflow.

Indispensable. BUT I have noticed a behavior lately that I find quite annoying: when I hover my mouse over the left side of the tabs, all of the tabs shift right by several pixels. Then when I move my mouse away, they jump back to their regular position. So every time I move my mouse around in that area, the tabs are jumping back and forth - it's really irritating and distracting. It breaks my focus and I hope the developers will stop it from doing that.

So usefull. Add this extension to other browsers (Chrome, Edge, Opera)

Nice, Thank you. I liked Tab Groups - this restores that lost functionality.

I can't send the tabs thru the Tree Style Tab on the left regardless if it's per tabs or per tree. When I select the tabs, I need to send the tabs through the tab menu at the top (ergo by right clicking the tabs at the top not the tabs on the tree style). Please fix. Despite this, it's an amazing plug-in.
