I’d like to also suggest the possibility of a fixed toolbar at the base of the app for easier navigation and access to key functions. Currently, using the two-finger swipe on iOS can be difficult, and the back and forward buttons that you can temporarily enable don’t stay on the screen consistently.
A permanent toolbar at the base of the app with buttons for Back, Forward, Global Search, Quick Open, and possibly a Command Palette in the future would hopefully enhance the user experience when navigating around 
Example of how this could look…
Thanks for considering!
