I'm a bit worried about the first one but it sounds like a good idea. Have you had any issues with scripts loading? I have such bad luck when it comes to scripts screwing up when I go through too many load screens in one session. I am definitely using the Media Keys fix mod now so thanks for that!
As for a UI mod that I have need would have to be SkyUI SE - Flashing Savegames Fix . Without it I literally can't save my game unless I wait a minute for my saves screen to stop flashing! I played for about 200 hours dealing with this bug before I found out about it's existence.
