Treat foreground and background color on a per menu item basis

[BenDunselman]

It would be an enhancement if it were possible to set the foreground and background color on a per menu item basis (in stead of on a per menu page basis).

Hi, @BenDunselman!

Thank you for suggestion! I will look into it later in more details. However, that most likely will require modification of GEMItem class, and in general I am very cautious of implementing such narrow use cases that require modification of global classes. It inevitably result in increase of library size, even of U8g2 version of GEM, even though it doesn't support colors, simply because it will use the same GEMItem class objects.

But potentially I can see it being optional feature (which may be enabled in Advanced mode or config file).
