this is only minor suggestion but maybe you could make Sidebar Widths setting adjustable more precisely than just by 5%.
I mean, now you can set it to 15%, 20%, 25%, etc. And I think it would be better if you could set it to 15%, 16%, 17%, etc. So by 1%. Or maybe even more precise by 0.1%
In other settings you use pixels so it’s precise at it can be but I don’t understand why in this setting the precision is limited to 5%.
