heading of editor page only partially on screen

[rhubarbdog]

As you can see from the screen shot both the microbit oval with 2 dots and python snakes are obscured.

Is it possible to scroll this heading off screen to create a larger programming area. With my default keyboard i can only see 3 lines of listing. With a 'programmers keyboard' which has configurable size, I can see 5 lines.

Functionality similar to this page is what i desire. So i can scroll within a textbox and scroll the full page.
