I'm not up to making my own character sheet, but so far I think we need a sheet that has everything except class-specific things like spells and fighter maneuvers on the first page. Then there is other, optional pages for class-specific things!
for example (in no particular order)
PAGE 1: The Base Character sheet
Lore, HP, AC, Racial traits, Class features, Background, Weapon/spell attacks*, Expertise die, Ability Scores, other stats, possibly money/inventory.
*this is one box
PAGE 2: Spellcasting
Spell list, prepared spells, magic ability, spell slots (total and used), save DC.
There is probably going to be stuff I forget, remind me and I'll fix it
If you make this character sheet, you're my best friend forever!
