Well, actually for me personally it had annoyed me right from the beginning. But I thought it would be fixed sooner or later.
On the other hand, it should be obvious that programmers tend to collect more then just a few snippets for their work. So a drag'n'drop behaviour should have been a no-brainer.
Anyway, I really like to see this feature. Maybe then the option "Edit Library" could be dropped.
Regarding your example: See how people use something ...

I never knew, that the snippets can be dragged into the editor ... I always double click them. Seems more logically to me.
But now I have another idea regarding this: _Create_ a snippet by selecting the code and drag the selection into the library, where it asks for a name and then gets saved. Further edits on it can be done as usual.
What do you think?
