CapnZapp, those same frustrations are what let me to start writing my own D&D tools app in the first place. What I am counting on in sharing it is that WotC understands players' frustrations and appreciates that I am helping to solve the problem using only data they already make freely available. I heard that there had been an attempt at some officially licensed online tools, but the developer failed to deliver.
I've thought I would like to provide several different options for character sheets, maybe even some level of sheet customization. I'm very open to thoughts on the matter.
Probably already on the to do list, but if I create a new spell, and save it (to my browser), it doesn't appear in the spells list when designing a character class or when creating a character.
