The one thing that I think the Encounter Builder really needs is the option to "Archive" old encounters. I like to keep the old encounters to remember the fights my party has had and how well they went. That, and it reminds me what they have fought before. It would be really nice if you could just archive old fights instead of deleting them

Either that or just some way to make the Encounter Builder look a little more organized for those of us who have a ton of encounters made :)
