I'm running a game of King Arthur Pendragon, and if you aren't familiar with it that game has a lot of handouts. especially with the book of battle. I wanted to give each player a form to fill out, which could easily be done by just screenshotting the form I wanted and putting it in a handout as an image which I'd then let the players scribble their notes on as needed. only, no scribbling. You should add the ability to draw and take notes on handout images, like maps and such. My players would note down their manors on our manor map, draw angry faces on the lands that are infested with giants, mark the domains of powerful friends and enemies. you know, if any of those things could be done in roll20. I could solve some of this problem by just making the map a 'page' of our campaign, and I've done that in the past. but if the GM doesn't show the players the page, then they can't draw on it, or even refer to it. Doodleable handouts would be much much better for my purposes because my players wouldn't need me to be the gatekeeper for looking at their own map and character notes.
