Batch export / save as is really important to me too!
I just cropped and adjusted 30+ photos, but now I have to go through 3 or 4 clicks/commands PER PICTURE, and also have to wait for the previous to finish, before I can do the next.
I'm also on the Affinity Trial - was planning to not renew my PhotoShop subscription (which expires this month) but this feature is giving me cause to pause and reconsider.
Is there any news on if & when the export/save can be automated too?
