Thanks for such quick updates!

For some reason, clicking on the canvas with the nudge tool with the document I've been using makes the program stop responding 100% of the time.
Import this image:

I still have an same issue with high index tiles being hidden. I have a document with 58 unique tiles. When I open it with PyxelEdit 0.2.20, Only 25 of them appear in the tileset window. I can now resize the Tileset window vertically. What I would expect is that tiles 25-49 would appear on a row underneath tiles 0-24. Tiles 50-57 would appear in a row underneath that. Instead, resizing the window just creates more gray space. And since the Tileset window can't be resized horizontally, I have lost access to tiles 25-57 through the Tileset window.
