First of all, 5 undos are too little for undos, if it were customizable, for example: you can set it to as high as 200 undos or as low as 5. Secondly, because of the lack of multiple undos, we can lose precious art pieces that took multiple hours or days. That's why i wish they added some sort of way to go through previous versions of the canvas. Maybe it saves the history after i dont draw for 5 minutes or leave the canvas, something like that. Just, please. It is so annoying and sad when i or my friends lose their art and cant recover it.
