Hovering over a directory while dragging selected entries

[Josip Tosic]

Hi,
if would be great if Servant Salamander would act as Exploder in this way: when I select directories/files and start dragging them, if I hover for, let's say 500 ms, over a directory that directory would automatically open and I could drop files into it's subdirectory or continue browsing through the tree in the same manner.

Wierdows Exploder works like this, but only if you hover over the tree view on the left-hand side of the window.
