I think this is a good start. The UI on Mac OS X is very buggy: both cosmetic bugs and usability problems. Basically I found it extremely hard to use -- level selection and creating multi-classed characters seemed a lot more difficult than it should be. The developer needs to spend some time running on MOSX, debugging MOSX specific issues, it sounds like. On a deeper level, this character sheet model won't allow tracking individual levels (at 1st I was a Cleric, I rolled a 6 for HP; at 2nd I was a Druid, I rolled a 4 for HP). A number of other elements of character creation seem untailorable (hp generation method, for instance). I look forward to seeing this product mature, but it's still not usable in a live setting, IMO.
