I feel like this repo is bait. The license is bad and violates the TOS but if they can convince a judge that it’s legally binding then they already have over a hundred targets who have forked it. They really messed up by including the shoutcast source and some Dolby code, although the Dolby stuff is questionable.
They are absolute garbage with wine. I think the only version that worked was the very first release.
It really depends on which features you are looking for. If you just want a solid editor with layers and plugins then gimp is pretty good. You can also try Krita for something a little less cumbersome.
Unfortunately most of the really nice editors are closed source and only mac/windows
I switched to just using Docker and nginx reverse proxy. It’s more setup initially but less overhead.
Current disaster recovery plan:
Step 1: cry
If you want to learn more, then you will need to move away from casa. Casa is pretty much just a collection of custom docker images that play well together and with their interface. You could grab an old computer, install Linux, and do more but you would expend more time and effort.
