Window options readability

[rodrigorhas]

I think the window options (currently as circles) should be solid black/white icons to improve the readability as we can see here

The options may be invisible at some cases (same solid color from colorpicker background)

Sorry for my inactivity for the moment, It's my final year of school before I work, so it took me a lot of time for now..
