hi Jiří! Thanks a lot for asking. I don't see this icon as my contribution but I see my contribution as a patch to the someone else's work. I think they should be choosing...
Thanks, that's in fact a good point, it should probably be considered to be a modification of the existing icon which I think is GPLv2 or later like the rest of the Geany code. So I'd keep it that way and mention it in COPYING.
Any thoughts on https://github.com/geany/geany-themes/pull/43#issuecomment-2488926364 ?
