I keep revisiting WhiteBoards because I love the idea of turning a design into a List. But the user experience of WhiteBoards is not good. It fumbles over itself. It creates shapes on top of shapes instead of auto-placing the new shape in an orderly place beside the previous shape, etc.
No need to keep naming examples. It is just not a pleasant experience. I'm fighting it more than I am using it.
I hope 3.0 solves WhiteBoards. Until then, Miro or Whimsical.
