Substrate (backlight) under the time counter

[DEHNCKA]

The background (highlight) under the time counter should adapt to the theme of the program (have its own transparent color from the theme file). I represent it like this:

(Segoe UI - 48 pt; substrate (backlight) - based on iOS7 Icon Grid) 2022-01-19_01-03-38.zip

Note: The dark gray border is just a background, like a viewport in a program or an image.

I will keep the simple dark/light for the slideshow timer
