While experimenting with the smudge tool, I noticed that when sampling from "Current And Below" the smudge effect was a lot smoother and accurate than when sampling from "Reference" and using multiple reference layers. I've included a video of specifically what I mean. Is there a reason for this? Could it be a bug?

I meant specifically the reference checkbox in the layer options. It only allows me to have one layer checked as a reference layer at a time. Is there a way to have multiple? I ask because I wanted more specificity on which layers get sampled when using the smudge tool.

Is it possible to not make the color panel moveable with the apple pencil and finger touch when touching this location of the panel. I keep accidentally moving the color panel sometimes when I tap there.

It seems to be when auto close is on. I made a screen recording of the bug.

The new Beta seems great so far! I really like the minor change to the interface/panels. The only thing this app needs for me is a quick shape feature and it will literally be my favorite drawing app for ipad.

I'm a bit confused. The Eraser tool paints with black while using a mask but Erase blending definitely doesn't paint in black when using a mask. I'm asking for erase blending to work the same a the eraser tool when using a mask.
