One thing I've come to do in many of the games I've played in is asking the GM for a handout specific to myself or a few other players to edit at my leisure for cheat-sheet reminders or session notes. I'd love to see a section of the in-room Journal that players can freely make, edit the text of, and edit the permissions of handouts in without having to ask the offline or busy GM to make yet another handout for one or more specific players. For instance you could make a handout that only you(and the all-seeing GM overlord) can see and edit called 'Thing to not forget to use'. Or another one called 'Loot Log' that you made but allow anyone in the game to see and edit. Or 'Secret Evil Side of the Party Plan' full of diabolical notes only shared with one or more other players. I know you could just stick it in a word doc on your computer somewhere but it's nicer to have them in the room. It'd be a small but very welcome quality of life change, I know I've been wishing I could just make my own darn handouts for a looong time, Figured I'd finally to the smart thing and suggest it.
