Actually it's possible to move notes using [CTRL]+[LEFT_CLICK], but it's not possible to resize them. It would be nice to add this feature and show arrows when the cursor is near the border of the note and [CTRL] is pressed. Reproducible: Always
I might be wrong, but isn't it already possible? Screencast: https://dl.dropboxusercontent.com/u/55247264/okular_note.mkv (Okular 0.17.90, self-compiled for KDE 4.10.5/Mageia 3 x64)
@Yuri: That's the popup window. I guess he's talking about the actual annotations (e.g. inline text notes, geometrical shapes...) *** This bug has been marked as a duplicate of bug 177778 ***
