I would have the suggestion that, even though CurseForge is its own mod loader, it would be possible to somehow use or transfer modpacks from there into NRC. That way, if your friends send you their modpack, you wouldn’t have to reinstall everything yourself. Every mod is just a .jar file, which you could either drop in directly or download via Norisk. You could theoretically use the same files this way, but it often takes an hour or more to get everything correctly packed into a modpack.
If there were direct integration with CurseForge, the same code-sharing system could be built into the Norisk Client, so that you could download and use the modpacks through it. This would make sharing mods much easier, even tho you friend doesnt use the Norisk Client
