The toolbar used in your mobile app (the one that is anchored to the bottom of the screen) is very nice for use on mobile devices (iPhone and iPad for me).
However, sometimes I am in the browser on the iPhone and iPad working in Dynalist, and it has a floating toolbar. I find this floating toolbar to be rather intrusive as working on an outline. Just a small suggestion, to think about using the toolbar from the mobile app in the mobile browser experience.
Warm regards,
Chris
