It would be very nice to be able to upload an image sequence (list of filepaths) as task preview, because it seems like qazu.task.add_preview can only take one file (image or mp4).
This is maybe related to https://cgwire.canny.io/review/p/allow-to-upload-several-images-at-once-for-a-preview-version but I cannot find info about what was done.
