It would be nice to cancel a generation if I had made a mistake with the prompt or reference image instead of letting it generate it

Suppose I type out a prompt and attach a reference image and hit “Generate”. But I realize I used the wrong image for the reference, It would be really useful to have a stop/cancel generation button so I don’t lose precious credits over a mistake. This stop/cancel can be a “X” icon button when the image is still generating.
