Better character orginization.

I'd love to see a basic folder system to better organize my ever-expanding list of characters and NPC's. As of right now, it is getting hard to find characters quickly among the rest even with the search function. My suggested solution to this is simply to allow the use of folders. For example, I'd love to be able to make a folder for a campaign and contain inside it characters that are in use, concepts or backup characters. I run campaigns as well as play in a fair share, I am also sentimental and like to hold onto one-shot characters and characters who have passed or were once in campaigns that have ended. I'd simply love to see a better way to manage the mess I've made of "my characters" tab.
