Indicate Used Spells & GM reset

So I was playing around with an NPC and something I missed (or couldn't find, tho I looked) is a way to tick off which spells I used and which are still available. Another idea that surfaced from that line of thought was a way for players to tick off which spells they used and give GMs a kind of "spell reset" button for when the party has rested and they regain their spells.

In Pathfinder, at least, I've always kept spells Known/prepared/slots/etc  on the general Bio&Info page in plain text so any player can see what spells I have and how many left I have.  This (along with an unholy amalgamation of custom spell macros) also lets another player "NPC" out the character if I happen to miss a session.

Oh wow that is quite the custom setup. But for enemies, for which I use the templates, it'd be easier if they were setup in the system itself, ticking them off for myself as I use them.
