ER: ability to Drag & Drop to folders in favorite toolbar

[inglorious]

although this is probably not easy to implement (impossible according to the programmer of xplorer^2)
having this feature would greatly improve my work-flow.
why? imagine you have your top 10 favorite folders in the favorite toolbar, now no matter which tab you might be on, you could simple drag & drop (copy/move) files and folders to your favorite folders without leaving the tab nor even losing the panel focus... now that would be awesome!
