Function Editor - Bigger Window

I've been using Node-Red for a long time and always moaned about the size of the code area for functions.
Today by complete accident I hit enter while in the function title field. Wow! I immediately got a much bigger edit area.
Maybe you all know this and I'm way behind the curve but I've never seen this mentioned before.

Hi @daxkamala

the expand button is just above the editor on the right hand-side:

the fact that hitting enter when the cursor is in the name field causes the form to click that button is not intentional and a quirk of html forms - but a happy quirk in this instance.
