I too, have just discovered the autosave feature within batch processing. Quite a relief! The IT strategy at my work frequently involves mandatory reboots without warning - often over night or over weekends when I try to get large processes going. I can't count how many times I've gotten back to the office expecting a new point cloud only to discover the computer rebooted. I can't even tell if the process completed, because I didn't know about the hidden autosave.
So my feature request is to simply make an autosave standard at the end of every time consuming item in the workflow menu.
Additionally, I think that the Align Photos process could be split into two segments(?): key point identification and point matching. For projects involving hundreds of images, the ability to autosave after point identification and restart processes at the point matching step would be a time-saver!
