can't I find the center of rotation? am I clumsy or is it really not in the program? I think it is an important thing to determine which corner point I can rotate or freely set it out of shape.
Another problem is that the layer position on the property panel is always determined by side points. You should be able to do this, optionally using the center point.
What features would you like to see in Pixelmator Pro?
Center of rotation or pivot point is very necessary.
