Showing the last generated image while the next one is being generated

[Raikiri]

Is your feature request related to a problem? Please describe.
Currently when you generate an image, the previous one disappears and the image field is empty/gray until the generation is complete.

Describe the solution you'd like
I'd like to not hide the previous image while the next one is being generated.

Describe alternatives you've considered
If it was possible, it'd be cool to gradually show the progress of the current image being generated, but it's technically difficult to implement.

This is already a feature, if you run ComfyUI with the --preview-method auto parameter enabled, you will get live previews of the image being currently generated within ComfyUIMini.

Very interesting option. However, I'd like to see the last fully generated image instead if possible.

I believe that has been added in the latest release, unless you mean something else.
