Some mods require you to have an asset pack for it to work. It would be good if there was an official way for creators to list the dependencies.
Then there could be a 'v' next to the dependency showing whether you have it or not.
Dependencies could be split in two categories:
I actually don't know if there are crashes if you are missing dependencies. (?) But still I guess you could flag it as necessary if you otherwise end up with floating objects or so.
Keep up the good work devs!
