Okay, per DMW's and Alethan's suggestions, I'm liking the idea of changing the weapons tab to 'weapons & armor". Also, removing the to-hit values for various armor classes, and just leaving THAC0, and adding a 'notes' field. And the bug about the HP will be fixed as well (already fixed on development version). I also like the idea of doing it like this:
Current HP: XX Max HP: XX
as Alethan suggested.
Also, Xaxyx noted that for multi-classed characters, the level and experience fields will not currently accept an entry like "2/1" or "4500/3000". This will be fixed as well.
Thanks for all the suggestions and bug catches, guys! The longer this list gets, though, the longer it will take for me to roll out fixes! I hope to have them all done by next weekend.
