- The UI refresh causes Ctrl+TAB to be much slower, due to the "adaptive" behavior
- The Options page has a lot of controls, but no explanation and seemingly no effect.
- I installed this to get a black vertical tab bar, nothing else. There is no option.

The Firefox themes also don't work to get a dark tab bar: they put the page also in dark mode. I just want the vertical tab bar to seemingly merge with the frame of my laptop..

This is good for Linux nerds that keep configurating and never do anything productive with their OS :-P
