This amazing fork has so far exceeded my wildest expectations and leaves EpicPen in the digital dust. Thanks so much for the developers.

I've pretty much gone through it's extensive capabilities and was wondering how difficult it would be to add layers to it's toolset. Layers, very much like you find in any drawing package like Illustrator or Photoshop. Just like one can save drawings (and then load them), this would be more immediate and would allow layers to be stacked. It would be a great help to me.

Again, an amazing bit of coding, and thanks for the tip about getting multiple displays to work. The resolutions were the same, but for some reason, I sometimes couldn't drag the toolbar over, and when I could, I could click one button, and it would freeze up on me. The high dpi settings trick worked.
