there are only 3 things that could possibly make this any better:
* collapsing power blocks by double-clicking the title
* getting support for feats, rituals, and traps
* a "character sheet mode" option integrating everything (doesn't have to be fancy, just a way to organize powers and feats with some basic preformatted stat and skill blocks)
IE 9 disables all plugins by default now in order to improve performance. You may need to manually re-enable Flash. Mine prompts me to do so, but maybe yours doesn't?
