Thanks for the idea, Castor, and for the offer to help. I'm accepting this one.
I've already looked into what native Linux would take, and it's very doable. GoMMO Studio is close to running on Linux today, but a few things need fixing first, like missing fonts and the way some file paths get handled.
I'm going to prepare a 2.1.1 patch that improves Linux support for the features Studio already has. It's a patch version, so don't expect every feature to be perfect yet.
Once 2.1.1 is released, I'll let you know here. Please try it on your setup and send your feedback through bug reports, so each problem gets tracked on its own. I'll work with you on fixing whatever is left once this initial release is done, then hopefully we can wrap up linux quirks before I release v2.2.
