Most editors offer color themes for textstyling. I know it is possible to change the colors of the editor. But it is pretty anoying to change the color of every element manually, espacilly if you need to switch fast between an overall light and a dark setting (e. g. dark for working and light for presenting some code with a beamer).
It would be great, if you could implement a few standard color themes, that can be edited, easily switched and shared. There could be a thread in the forum or a special page here, where one can upload a created color theme for everyone else.
