In my experience the drawing feature is useful primarily to GMs. As a gm i use it to draw simple impromptu maps when i have nothing prepared, and it serves that purpose well. As a player, i have seen it used to draw a campfire when one is placed. Beyond that, i have seen bored players disrupt the game by drawing all over the place. What i suggest is a system like fog of war where if u want to limit, or cancel player drawing, you can. I would also like to see the ability to give individual players the ability to draw, only in certain tiles. For example if a ranger casts spike growth, i could allow them to draw over the area of the spell. Another implement for individual drawing limitations is that you could have a tavern room area set up during the week/weeks between sessions and give each player drawing control over their room, so that they can immerse themselves in the game during the week. In my opinion, the worst case scenario is that this feature would be rarely used, and the best case is that is would give the players more creative agency, as well as giving GM's more control over rowdy players.
