Hello, is there any reason why Solus Plasma isn't in the distribution list? If there's no reason, wuold you please add it?
Solus is already listed on https://community.kde.org/Distributions. If you're talking about https://kde.org/distributions/ instead, that list is a curated list of distros that offer a first-class KDE experience, Solus is not even shipping Plasma 5.21 yet, last I checked. The Plasma session seems to be an afterthought, which makes sense since Solus has their own DE.
I think OP is talking about "Platform" combobox in bug reports.
