In file tasks.sgvz are defined visuals for different states.
When modding default breeze theme I’ve noticed that there is annoying limitation to hover state. When mouse cursor is above particular icon it completely replaces previous state.
It would be much more flexible for UI designer if hover state was layered on top of previous state. You already do this when it comes to progress bar so it should not require a lot of programming work.
With this change we could have or example normally working outline selection
or something even more fancy like some transparent gradient acting as glow
