I have voted for similar ideas, but I wanted to add more specifics that I've come up with myself.

The idea would start with simple things like a friends list, chat feature, mod sharing, pack sharing and world/server sharing. People have suggested these, and I have upvoted those.

My next part is a system where you could share a custom profile you've made, add a mod to it, and then after you've tested it to make sure it works, you could update the profile for all your friends.

There should be some kind of notification to each user when someone does update a pack that tells each user what mod was added/removed, when it happened, and what user updated it.

That brings me to my next idea to add on to this system. Admin permissions that would allow other users to modify your pack's different parts. This one idea, if blown up to a larger scale, could allow content creators to build teams to maintain packs for their audience to play on a shared server.

which brings me to my last idea for this system as of now. These shared packs could be preloaded with server IP addresses (managed by the owner of course, not CF,) that everyone who has access to the pack could play on.

That concludes my idea. I think this sort of system could turn curseforge into the discord of minecraft (or games in general) modding and revolutionize the ease of use for modders with ever-expanding ideas. Please Upvote, Gamers👍
