Allow to create custom palettes for colors.
32 colors could be enough, even if I would prefer to have a color wheel to select any color I want (eg. #a4ff60), but the default one are not the one we already use in school. It would be nice to have the possibility to specify color palettes and name them.
You can now choose any color you want with newly added color wheel. Custom selected color will be added to existing palette of 32 colors in a separate row so you can easily pick the same color again.
