This is a really cool device. The only things I can think of that would improve it are....
1. More shiny. Redesigning the application with a custom skin and buttons would make it cooler
Totally unnecessary though.
2. The ability to upload poses to go with a charset. That way you could upload all the blizzABS poses for a character (a list of the poses could be shown to the right of the charset. And when you click download, it could ask you if you want to download the poses with it.) This would really be cool
3. Member accounts (so a member can modify and delete their submissions). I know we've all mentioned this before, but I felt like making a list
It's really cool that you put the time into making this.
