I had no idea! It seems like it was a really unruly project to manage, but it’s a shame to lose the centralization of having one app that can configure anything. I don’t see any problem in having package management split off into Myrlyn, but it sounds like Cockpit is much more limited in scope, which is a shame, since handling the edge cases gracefully was what made YaST so useful.
Here’s a source for others who didn’t realize.
Okular is the way to go for anything that’s typed, it has a lot more capabilities than Evince. For handwriting, I’ve used Inkscape, and Libreoffice Draw. They’re roughly similar in capabilities.
