On the text not fitting here when it runs out of space issue: I'm playing a rogue 2 / warlock 6 and I am already out of space in the summary box.
I've been trying to think of solutions all year. I'm not a power excel user like you. But what if text overlap in this cell generated an additional cell somewhere else in the sheet. OR what if the layout (maybe for 3.0) were to be altered so that The Sumary is a stand alone sheet. That would give you some extra room on this sheet for new features introduced in supplements up to and including xanarhar. Or just to make the current sheets roomier.
I realize re-linking cell addresses is a huge pain in the purple worm, but it would give you a whole page and even account for overrides to be a standalone sheet. Or maybe it's a bigger road block than I can understand.
Either way, I really appreciate your contribution to the game. I'll try (as everyone should) to remember to buy you a beer or few on PayPal for your efforts when I'm near a computer.
