This is a constant thing for me as well. I also constantly find myself using the Back button on my mouse to try to navigate back to previous notes or tags as I browse around, but of course that doesn’t work either. I hope this is considered.
Swiping with two fingers to the left or to the right of the screen on iOS moves across the navigation history. Alternatively, the History Navigation controls can be enabled in the … menu in the top right corner of the editor.
