Give Phosh a working browser
Neither Firefox or GNOME Web work decently well with Phosh at the moment. Firefox is apparently being discussed here and here. GNOME Web is unfortunately broken on Wayland at the moment. Given that the graphical phone UI use Wayland, and that a web browser is quite important, it's quite annoying.
Investigate why it's broken on Wayland.
Force the use of the Wayland backend on Phosh and Plamo. It works better on Wayland anyway.
Try to move, if possible, buttons to the ">>" menu by default.
