Noticed this while checking progress of training and checking the git to confirm: They changed how preview images are shown on the Review your Model page after submitting your training are laid out. You can now click to expand to full res instead of just right clicking and opening in new tab (or saving).
Unfortunately this is actually regression for me: I can now longer just right click and DL every preview image and now have to maximize everything then navigate in two dimensions (pressing right at the end of a line doesn't even take me to the next line!) to get to one I can actually right click and DL for my records. Having a button to DL all epoch pics as a zip, something I've asked for since I started training years ago, would fix it. Otherwise this is going to be a bit annoying.
