I've used JSGME for years in multiple applications and has proved itself as very useful.
I have suggested one could make presetup orbiter mod selections for download with it.
Funny thing is I've never used it with Orb., never felt the need, Orb has a very simple file structure, and strangely even with a massively modded setup (and chaotic modders) have seldom had conflicts (or not ones I could not simply change).
The only time I think it would be good is with tiles (that seems to go wrong very easily and is VERY hard to fix), but the idea of several GBs of bckups puts me off!
And talking about neglected/forgotten addons - there is an openly released addon manager for orbiter on the hangar
https://www.orbiter-forum.com/resources/orbiter-addons-manager-oad.1011/
does it work? no idea, like I said I don't need one, but it's got one official approval and has been downloaded over 1600 times, so if it doesn't a lot of peeps want one!
And if it those maybe it can be tested and given official approval (solve all this meandering)
