Going to buy some more RSN. I also left a comment in the blog. Looking good, waiting for more. I know you are thinking about objects, but I would say there are large number of things out there already, so I say you concentrate on tokens and
"perhaps" adding in some portraits. So, for example if you have a pack with 8 goblins, perhaps 3-4 portraits. Of course since I use maptool and it has both top down tokens as well as mouse over portraits, perhaps I am just a big biased on the need for such things.
