GNOME and Ubuntu usability issues

When I open up 10 nautilus windows (entirely normal now that spatial is the default), they all get grouped together into one bar in my window list at the bottom of my screen. Ok, that's fine. But when I try to drag something from one window to another, there's no way to access the window list to raise the destination folder.

With each nautilus window in its own bar in the window list, I simply drag from the source application, hover the dragged object over the destination window's bar in the window list, and the destination window is automatically raised. This doesn't seem to be the case when all the windows are merged into one big "File Manager" bar.

Ideally, when you drag something to this conglomerated bar, a list should pop up giving you the option to hover over and of the windows contained within that list, and raise the corresponding window.
