The "Update" feature constantly fails to update my layouts. I understand how it is supposed to work, but it does not, or at the very best, does so intermittently. I have updated my layouts after adding new book tabs and then need to open those same books over and over. If I "update" a layout and then then close the app, it stays, but not by the update feature alone.
As for snapshots. They seem to appear at will. If I delete the latest snapshot, I wind up deleting the whole layout it purported to be a snapshot of. Snapshots proliferate on their own. Then I need to waste time deleting them to clean up the layouts. It would be good if you could work within layouts by selecting multiple layouts at a time. specially to delete the ones not wanted.
