 Too high customizability for such rare usecases will just make you happy, but others including me won't - they are just confused that "why such too much choices are here?"

+By the way, "auto hide tab bar" feature doesn't provide any its own keyboard shortcut to toggle it because the feature is included in TST mainly to simulate Firefox's default behavior in the fullscreen mode (started by the `F11` key).

 ### [Ability to disable animation effects around tabs](https://github.com/piroor/treestyletab/issues/499)
 
 [If Firefox introduces new preference to disable tab animations](https://bugzilla.mozilla.org/show_bug.cgi?id=556717), I'll apply it for TST too. Otherwise I have no plan to implement such a "no animation mode", because it will make TST more far from Firefox's plain codes. Now I have only a few resources to maintain TST, so I don't want to increase the risk that I give up to update TST for future versions of Firefox which will be continuously modified.
