Well, first of all, let me say that people lamenting over an open source project is very sad.
The comment I've linked is from a Neo Launcher contributor and, as you can see, there's been continuous work on the project.
Yeah I know, that was my original point. I think it's fine to be sad that an open source project is stagnating, especially if you're a keen user but don't have the knowledge to change the codebase yourself. Thankfully I didn't see anyone being rude or demanding, that's the real bad sign.
