Description

Created attachment 6777 patch

Hello,

Patch adds a popover window where you can select a color for a tab and a title pattern. If pattern will be matched on any tab, selected color will be applied.

Patch is still missing an ability to save settings to the disk, but I think it could be landed separately later.
