Is there a way to mark characters as your active character so they appear at the,top of the list of one's you have created? 

I realise this is a minor thing as most of us, myself included, can only create six characters, but I like creating random concept characters just to see what they can be like and its a little annoying to have to scroll past five of them to get to the guy I actually use for games.

As far as I can tell, there is no way to do this right now.  It might be planned, though.

I would settle for showing in order of access, so that the character I opened (or edited?) last shows up first.
