I can't see the logic in your "eyes resting" by having a theme with that high contrast :/
I can't see the logic in changing a theme at all... dozens of engineers who know a great deal more about ergonomy than you and me and anobody else on this forums work on an operating system's default theme for months.
I use all my installations with default theme, and I don't have any issues with it. The only thing I could imagine would be to switch to "big fonts" theme in 30 years from now, should my eyes get worse (but hopefully, we'll have some kind of eye implants until then...).
couldn't it be possible to set ide colors(themes) manually? or do you plan it? :lol:
The IDE currently uses what wxWidgets figures as the "correct" thing from querying OS settings. Not sure we actually ever change one control's colour.
Even if I understood why one would change one application's colours manually, I would not know how to do it, anyway. Mind you, it's not just about setting the background of one or two controls, it's a bit more complex.
