Pfhoenix, I applaud your efforts because I think they're the most likely to result in the kind of e-sheet solution I've been looking for. What you've got here is awful nice. I like the fact that you've deliberately picked your battles about what to calculate and what to leave user-defined. I've long felt that many sheets go too far in one or the other direction.
It seems evident to me that you could do a printout for power cards and even calculated weapon damage, so I'm going to assume that if you're not doing that its for legal reasons, and therefore I won't bug you about it.
As usual, at this stage in my experience with the game, every time an e-sheet does something weird, I can't tell if the sheet is wrong, or my knowledge of the rules is suspect. In this instance, it's my ranger's hit points.
My 2nd level Ranger with a 12 CON has 29 hp by my reckoning and 34 by your sheet's calculation. I'd love my calculation to be wrong.
As far as I can tell, it's 12 for Ranger + 12 from Con + 5 from 2nd level.
That's 29. Whence comes the extra 5 hp?
