Since the popup editor may be pulled to cover the whole browser except the right hand column, it would be nice if the breadcrumbs included the name of the function being edited. (You can pick the info tab in the RHS to see this, I usually want to refer to the debug tab)
Below the breadcrumbs line is some wasted space. If this area is accessible to Node-red, could it be used to display a line or two from the function node description (if any)?
It's not "wasted space" - it's the space/bar for the buttons and is a common component across editor pages - but yes on a full page it is rather empty.
But yes the function name would be useful.
I know, you won't stand for that Dave!
I considered that using this space for part of a node description might encourage me to document my nodes.
It would probably sufficiently annoy some that they would be deterred from documenting.
I'm happy to abandon proposal part 2.
