+1 for this. Keeps all of my characters nice and tidy. Whenever you level up, you pick your new abilities from a list of options, and then it'll autofill that into your character sheet. It won't autofill your spells, though, so I use a different app for that. The only downside is that some of the abilities for certain classes aren't named correctly, I assume due to copyright issues. But the names are pretty clear what they're referencing (example: Agonizing Blast = Potent Cantrip).
