I've just found Roll20 and first I've got to say that its EXACTLY the tabletop gaming tool I've been searching for. I've tried all the others and finding the right token for simple things took far too long, it bogged down the game. Thank you all at Roll20!
One thing that I've found a need for already is that I've already uploaded a number of ready-to-use maps and its getting kind of cluttered having to go through them all to find the one I'm searching for. I could just make folders on my computer and upload just what I need in the short term, but I like to prepare for multiple different paths my players could take. Some sort of simple folder system would be great for organizing our maps.
