Oh, so colorful
As it was the case with borders, I took the LibreOffice color requester as GUI blueprint for my Leu color chooser, Basically it’s the same as for the borders. The only difference, you need two of them, one for background one for text (in principle a one more for border color, but I left that out for now.)
Leu also got a own Page now where always the newest version can be found and some central information about it. For now I will not keep a history for it, because still changing too much things.
