The Inscription thing I don't think we can do anything about. The planner has no input methodology to handle inscribed spells, and I don't know that I want to put that in (seems like a bit of overkill from a character planner angle). If the user really wants to, they can always write it on the printout when they inscribe spells.
I do like the idea of breaking down the box into three sections, one for each potential class. That solves several problems I have been wrestling with regarding listing the spells. But that does clash with how much room we have available on the page. I'm just about resigned to moving the spells to Page 2 and putting something else in that spot.
Given all that, what we really have is the difference between picking spells at level-up (limited total spells) or picking them at the bar (all spells available), and how we show that on the printout. What would you do in PnP D&D? Probably you would just list the memorized spells. But we don't have that capability in the planner (it's the same issue as inscribed spells all over again).
I suppose the best thing to do is figure out how many possible spells a player could have. Probably Druid or Cleric has the potential to have the most spells available at once (again, discounting inscribing scrolls). If I count up those spells, maybe that will tell us how many potential lines of text we are dealing with.
I will, don't worry. There will be a tweaking phase once all the sections are in and working.<edit> BTW comic sans is still there..... kill it! kill it with fire! </edit>
