Explorer-style Navigator

[CJ]

I would like to see a dockable/floatable, Windows Explorer-style navigator from which we can drag files to open.

Thanks.

For a (drag and) drop target, just create a Windows shortcut
for textpad.exe then drag that shortcut onto the Windows QuickLaunch toolbar (a portion of your Windows Taskbar)

{ this requires your taskbar to be set as "always on top" and the QuickLaunch toolbar set visible }

How about a favorite directories list, like NoteTab has? Instead of the opening directory following the current file (already a fine option), you can choose which directory the "Open" function uses from a list which you administer.
