These are two projects I found through asking lumo.proton.me
But I do not have any experience with any of them. And little with Github.
So I am concerned for knowing, that many opensource project are edited through Github and it is one of the bigger FOSS islands we currently have. Therefore I just shout out some loose oportunities, so might more knowledgable developers follow with more informed opinions ^^
