Also totally agree with this. I play with friends, and most of the time this isn't an issue. But once in a while, one friend goofing off and drawing something funny turns into a derailing event that gets everybody off task. Even with the ability to clear all drawings from the page, it doesn't prevent new drawings from being added immediately afterward. I'm not a particularly confrontational person, and even a minimally assertive request like "stop it please, so we can get on with the session" can be easily misinterpreted as combative when all everyone's trying to do is have fun. Creating an option to broadly disable and enable this feature where appropriate would save my group of nerds with ADHD a lot of frustration. Kudos if you go a step further and allow disabling/enabling player-by-player, so the DM can put misusing players in "drawing time-out" without having to take the drastic step of booting them from a game or ending the session early.
