[BZ#779610] allow resizing the notes popover
Submitted by Matthias Clasen
Link to original bug (#779610)
Description
Something I've wanted to explore for a while, but never got around to doing: It would be cool if GTK+ supported user-resizable popovers, we could use that to make the notes popover adjustable.
This is not an easy task! More like a research project inside GTK+
