We already have arrows that allow us to go up and down (to the next or previous note) in annotation files, but it would also be useful to have navigational arrows to go switch back and forth between most recently viewed/edited entries. I often find that one entry leads to another (for instance and entry on Lot in Genesis 19 led me to an entry in 2 Peter 2:7). Being able to switch back within the annotation file would be handy.
