Description Tiar 2020-10-11 15:07:39 UTC 
SUMMARY
When I saved a reference images set, Krita was not responding for a few seconds. Depending on a size or number of reference images, it might take a long time, so I think it should be done in a background thread.

STEPS TO REPRODUCE
1. Open a file with reference images.
2. Select all images and go to Tool Options of the reference images tool.
3. Use "Export Reference Images Set".

OBSERVED RESULT
Krita doesn't respond to input; it looks like saving happens in the GUI thread.

EXPECTED RESULT
I can do other things while Krita is saving reference images.

Show the busy cursor when saving a reference image set

It's okay to block the ui, we just need to give the user feedback.
