Massive waste of space in the raw editor

[DerEmder]

Well, the tiny window for editing a raw dashboard yaml is just annoyingly small and not even resizeable (let alone moveable). The only space I have for editing the yaml is the tiny row on the left (marked in red) and a tiny (part-)preview on the right - which is not even dynamically resized (I have to use the scrollbars all the time). Please make this a real editor, dynamically adjustable and as big and flexible as possible.

omfg, I did not know that. Thanks for this hint. I wonder if this is new.
