Feature Request: External Border color and width

[Saijin-Naib]

Description
Sometimes I find I would like to have more visual separation of TinyBit Launcher elements like search, results, and dock, while keeping them visually consistent.

Solution
I would love to see the ability to set an external border, with settings for color and width, to have this visual separation.

Additional context
Pop-up menus in TinyBit already have this, so it would integrate well, I think.

This would add a lot of additional properties. I think we need a way to filter/search properties.

Is there a tabbed UI component that could be used to subdivide the Theme and Layout submenus? Would that help?
