The "Add to Collection" window should be more intuitive.

It’s not comfortable that the window only has space for 5 collection options shown at a time.

It would be better if images were draggable and a div would appear showing collections you can drag it into so I don’t have to scroll anymore.

Scrolling is already a laggy pain on my computer when so many images are loaded in due to infinite scroll. So having to do it for every image I want to save that is no good.
