@arran4 @voracread With some specific packages there are conflicts between different versions, so you can only have one at a time installed even if they have different slots. I think a few of the core KDE packages are like that. I know that I had to remove some parts of KDE 5 when I installed KDE 6 on my Gentoo system.
@Bali10050 Incidentally Evan (Boehs - the guy you forked from) is somewhat active on Mastodon, so if you wanted to get in touch with him it probably wouldn’t be hard; he might help point people toward your fork. In case that information is helpful at all.
My capacity to contribute would be extremely limited, but I starred the repo at least, maybe I can chip in a bit at some point in the future.
