[ENH] - YAML editor window is too small

[kcpevey]

Feature description

The YAML editor window is only 11 lines long. My YAML specs are around 40 at a minimum but can be much higher. Its very difficult to work in a 11 line window.

The screenshot below is my screen at 100% (i.e. no zoom). There is a lot of unused space at the bottom, so there is plenty of room to expand this window.

I recommend this window be expanded to at least 50 lines.

It would actually be great if the window could grow as more lines were added such that there is no scrolling, ever. But I understand that's a bigger effort. Just having 50 lines would go a long way in usability.

Value and/or benefit

Significant increase in easy of use, and less frustration.

Anything else?
