@marcedwards, Apple claims it's already an option:
@atnbueno @marcedwards Watched the section. Does not look like the stance has any changes from the June videos:
> “too much of it or in the wrong places can be perceived as visual noise.”

> “Tinting every glass button in the toolbar can be distracting”
@marcedwards Whatever fixes the contrast issues – I’ll take it.
But this also creates other issues, like having primary and secondary roles of buttons – color was the primary means for this before. How would you solve this if all buttons get tint-colored? Different colors? 10 pt dashed border? :)
Also this is not a solution for macOS – in 27in full screen app case it would become some Christmas tree parody very fast.
