Allow customisation of active item background color

[pedropombeiro]

Is your feature suggestion related to a problem? Please describe.
It is hard for me to distinguish which window is going to become active when using AltTab (maybe because I'm using the dark OS theme).

Describe the solution you'd like
I would like to be able to customise the color or the item background color to make it stand out more from other items.

Did you try the Windows 10 theme? It's high contrast

That works, although not ideal since I'd prefer not to have a square rectangle around thumbnails in macOS (looks so out-of-place 😉)
