A possible feature at least I would love to see in the loader would be, be able to leave notes for each script so we can tell what works for what champion.
I'm sure some people got used to or can simply remember what works for each one, but some times with so many scripts calling themselves AIO, or Bundles, it's hard to tell what Champions are supported by it. Of course, we can use the Database and search for the name and see what is available for what champion, but that brings a few problems like some scripts are not featured there so you have to dive into the forums to find them, or if you're about to get into a game, you just selected your champ and you forgot what is available for him, it takes those precious 50 seconds from the champ select screen to find something, and that's on top of selecting rune pages or editing previous one.
