I usually keep my downloads window snapped to one side and I drag artwork over in the order downloaded, but sometimes I'll miss the drop zone and it loads the image to the window instead of uploading it. When I backtrack I lose my progress and it's infuriating especially when it was many files that I'd already dragged.

It'd be nice if it would ask me before navigating away, and even better if it didn't forget what I already dragged over if it does navigate away. Or if the entire page could be a drop zone
