I had forgotten that this is a new feature
and so i used it very self-evident in the 11.1.x betas
to double existing items for an start for an new macro.
And it works very well.
Not only to copy&paste items.
I even can paste plain text and get an new snippet item.
Back in 11.0.5 i quickly miss this feature badly :-D
SO thanks again Yutaka, well done!
