Hey, just bought this today, mostly a good experience so far.
One bug I've run into that's especially obnoxious is in the editor, at some point (repro steps unclear at this point), the editor starts edge-scrolling; when I put my cursor near the edge of the editor, the editor pans in that direction. That's moderately annoying, but what pushes this over this edge is if I have any nodes selected, those MOVE the same amount as the pan. So basically everything pans except the node selected, which moves. It's frustrating and I get dropped into and out of this weird state at random, though it seems to happen most when deleting nodes.
