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...
Sacrosanct, very true, I'm hoping there are no issues. I've contacted WOTC about getting explicit permission to use the basic rules and the character PDF, but have yet to hear back from them (I'd imagine they have a lot of requests to wade through).
