Hi tonypond
For mirror and flip you can set the width and height to negative. I find that more useful as the actions you refer to do that anyway and are redundant.
I didn't add scale as that's based on image size and I thought it made things unintuitive because you can change the texture size with the set resolution action. It can be done with the set size action if it's really needed.
So I think I purposely didn't add those two features.
Any pasted objects should draw exactly as they are overlapping the paster object. So that last bit should be true. I don't think you can load an image into the paster object but you can load it into a Sprite and paste it.
I'm glad you find it useful but I'm avoiding updating it unless I absolutely have to.
