If you have hundreds of folders, it's burdensome to select and move images to a second folder which can be hard (and certainly time consuming) to find. Would be great if you could select the images, then click on the "Recent Sources" (or "Favorite Sources") triangle in lower tool bar to bring it up, and then move your selected images to that folder. What happens now is you lose the selection when you click the triangle.
Or I'm open to some other clever method of getting the two folders easily that I don't know about. It's much easier with Collections where you can make one a target and then move all images in with a simple "b".
