Changes that I made:
- add "scrollbar.thumb.active_background" to all themes
- for dark themes: scrollbar.thumb.background is darker than hover (fg4
from palette for background and fg0 for hover)
- for light themes: scrollbar.thumb.background is lighter than hover
(fg4 for background and fg0 for hover like in dark theme case)
Those changes is consistent with VSCode gruvbox theme and other
applications.
For active_background I chose orange color, but we can use cyan color to
match vscode theme.
UPDATE: decided to use blue for active scrollbar as this color is used
as accent in other parts of gruvbox themes
Release Notes:
- Improved scrollbar colors for Gruvbox theme
