Gave drawpile a try, along with  iaido can definitely see getting a lot more use out of this, makes me feel all tingly during the open canvas era, which is not as easy to pull off anymore, though regardless seems it has a lot more options than OC did, its a little funky when it comes to blending colors, but overall it's pretty darn solid, super customizaburs.

Apparently it can handle up to like 20 people, would be interesting to like maybe host giant art collab artpile parties or somethin'
