renaming and/or re-ordering the scenes in the project panel

Im a bit of a neat freak and like my workspace to be labeled and organized. I know...not much like an artist but, I'm a designer too and like things organized.

I'm working on a music video using Character animator and AfterEffects. I'm pretty much filming each cut with my puppets and naming the scenes as I go. However, my first few scenes were created by "add to new scene" which gave the scenes the puppet's names. Needless to say, its a bit confusing and I'd really like to change the names of some scenes. How does one do that??

Also, it would be great if I could drag the items in my project window into groups of scenes, audio, puppets, etc... Is there a way to do that?

Thanks.
