Losing place in large collection, or way to get back to where you were?

Hi!

One thing I don't like how collections work. If I'm working in a collection, and by accident, maybe dragging a photo to a different collection and by mistake opening that collection, I can't easily navigate back exactly where I was. it brings me to the top of the collection.

Now, I'm going through a 4,000+ collection for a travel book. Maybe i'm half way through it. If i want to do something else, I can't get back to the precice place.

Any ideas.

I wish you could open 2 or more collections in floating windows.
