Dear Yoame,
I stumbled across your question searching for an answer myself, and I think I have found a solution.
Using a third-party program, it is possible to restore the exporer navigation bar to the last version in which the classic drag and drop function was still available.
The program in question is called Windhawk, they are "The customization marketplace for Windows programs", or so they say.
I do have to say that this program is not a native windows feature, but rather a workaround, so be aware of any possible bugs and proceed at your own risk.
For me it has been working great so far after my first hour of use.
