I found a big problem with icons when developing for light theme.
When I need to add some image to list, button or any other fucusable control - then it does not look right for both focused/unfocused states.
This is becase most ocntrols use darker blue for focused satate comparing to light background in normal state.
So if I do dark image to looks best on light background - it becomes invisible on focus/tap on control.
So doing for lligh theme one has to use specially designed icons with some llighter outline etc..
Doing this for dark theme goes flawesly. At last in Beta 1. Going to try B3 now.
