1.) work on an update for skyrim that adds a universal package format for user mods that contains data needed to make them work on all platforms. the skyrim app itself should only install platform common and platform specific data for the mod on the other end, not data for another platform.
2.) add a public (but moderated) ftp for creation kit mods. all ports of skyrim should be able to parse it as a user repository and fetch mods to install.
3.) it is likely that such an update as in 1 could break compatibility with mods on the pc side, so an update to the creator kit would be the recommended next step which could export universal packages and upload them as well.
4.) skyrim should store mod content in a subdirectory instead of the main data directory to prevent a collision with actual game data. the overwite of data should only happen in memory.
5.) if an update for a mod is detected, then skyrim should provide an opportunity to install the update at startup.
6.) add a grief report button that allows complaints to the author about things like mod breaks dlc, etc.
7.) add a file a complaint button that tells user repository moderators about inappropriate content such as child porm in a mod so that proper action can be taken.
8.) there needs to be an uninstall option too for mods.
