Minor correction to your minor request: Soul gems are used to recharge items, not repair them.

Otherwise I agree. It's a small thing but it is irritating. Especially because I almost always have only one type of soul gem and forget there's another one, so I sit there for a few seconds wondering why it's asking me this before I remember.

Ah ok. Well it's the same either way - if you've just gone one available to use it should just use it instead of asking you to pick.
