Good idea!
Useful when we drag on our bookmark bar.
But sometime we want drag it to a special place:
Can you add option or a way to left us put a bookmark at a desired position (not on top) when you need it .
By example:
If we drag on the folder icon : put it on top of it
If we drag into the folder : let us choose the place where to put it.

That particularly need when i use the full bookmark page.
