Such a tiny window to edit here on a cell phone

Install the site as a PWA, removing the location bar and the Chrome tab switch bar gaining lots of screen real state

There is no difference, still 3 lines visible.

@Falco

Enable Android Navigation Bar Gesture mode, which removes the black bar at the bottom and leaves more space for the app you are using

I don’t have that option (maybe it depends on the android version).
But since I do not start a topic that often and ever more rarely with my phone, there is no problem for me. For replying the 8 lines are enough
