A quick tiny itsy bitsy little feature which was actually a pain, but necessary on our way to a better stack experience.
Now, if you do not set a stack key image, the default slice chosen for the series thumbnail will be the middle image rather than the first image. This of course makes much more sense, as rarely is the first image representative.
This same middle image will be the start position for stack viewing in Quiz Mode, and soon the same will occur in case view.
We have also gone back and set the middle image as key for each stack which had not had a key image set; all 16,175 cases ! But don't worry.. if you have previously set another image as the key image, we didn't touch that, so all should be good.
Thanks, and happy case creation.
