Take a screenshot of your full screen, paste it into a notebook, right click the image and choose `Crop Image...`. This operation is *extremely slow*. On this Windows machine it literally takes 10 seconds for the cropping UI to appear with such large-ish images (yes, I timed it with an 1366 by 768 image). I'd consider this a bug. Question 1: Has anyone implemented a custom version of this that performs well? Would you be willing to share it? Question 2: If I implement it, is there an easy way to integrate it into the context menu specifically for images? (The context menu is different for each type of object). Question 3: Is this so slow on other platforms as well, or is it a Windows-specific problem?
