Duplicate mod detection

[adamcirillo]

Role

Play modded minecraft

Suggestion

would be nice to have a button that can detect if there is different versions of the same mod installed

Benefit

To make it easier to find and fix problems as sometimes if pack updating plays up you can have mods with more than one version downloaded and save having to reboot and check the mod list to remove them

This issue got interest from me after releasing a new Modrinth test version of a pack and realizing that the PrismLaucher updater had downloaded new mod versions without removing the original versions, combined with a realization that unlike Forge, Fabric will still load and the version that loads up on start becomes racy - I didn't even notice until I was looking for a bug and realized the undefined behaviour I was encountering as a result of this.

This was somewhat jarring as I just moved over to managing modpacks with PrismLauncher from ATLauncher which does handle this in a more "correct" manner from IMO. (but ATLauncher can't manage LWJGL issues or server/client dependency metadata anywhere near as well as Prism, so Prism is still winning overall in terms of managing pack creation from where I stand).

I feel that this deserves some prioritization based on the experience with Fabric and duplicated mods after a Prism mod update.
