I have just updated to version 7.0.
The highlight colour for books in the library screen has changed to a sea-sick green with white text. But worse, the highlight colour if one of the cells within the line has been selected is a bright yellow with almost invisible white text. It is almost unusable.
Earlier versions were a two shades of blue, more restful and easier to read.
The only options for colours seem to be to change to a dark theme (dark = black).
Is there any way to change the highlighting colours or text colours in the light or default theme?
Or could I make changes in Windows?
