it would be nice if you do a cooperation with modrinth and do it like in the modrinth app.
There, every "instance" has his own serverlist and worlds, and his own mods and his own version.
And you also can add mods from modrinth directly in the launcher so easily and update the mods to the latest version for the selected minecraft version. So i can copy my pack and easily change all the mods by 2 clicks from 1.21.4 to 1.21.5. And each "instance" has his own reccourcepacks.
