The idea is inspired by #3407 I agree with - some users prefer dark themes and Geany currently doesn't ship with any dark editor theme and cloning and copying themes from geany-themes is an extra step which may discourage less experienced users. One option would be to have one "blessed" dark theme that we'd ship with Geany - I'm just afraid of the amount of discussion it would require to agree on the "right" colors :-) (see #3013, and these were only 4 colors)
So what about taking all the themes from geany-themes and copying them under Geany's `data/colorschemes`? I think the development github repo of geany-themes could stay as it is, we'd just update the themes in Geany once per release similarly to ctags or Scintilla (in fact, I have been doing the very same thing for the macOS release for many years).
The pros I see are: 1. Copying the themes is done once by us and doesn't have to be done N times where N is the number of Geany users 2. Users don't have to discover the geany-themes repo and can try various themes out of the box - especially useful for someone evaluating Geany whether it's a good editor for him/her 3. Theme files are small so no big problem distributing them in the release tarball 4. The extra work needed to copy-over all the themes from geany-themes is small so it's not a big maintenance burden (and probably not a big deal if it gets forgotten for some release)
Are there any cons? What do you think?
