[QGIS-Developer] Unabbreviated expression evaluation preview?

[Matthias Kuhn]

Hi Hannes,

Good request.
I think it's mainly the way it is for not cluttering the - already heavy -
interface too much. And potential performance problems if someone tries to
put the complete qgis source code into the preview (... that might lead to
other problems too ...)

I'd propose an on-demand popup and integrate a "copy to clipboard" action
at the same time.

That would justify a feature request on github.

Cheers
Matthias
