Allow folders to remember window position
Allow folders to remember the window scroll position last viewed.
If you have a folder of 100's of images and drill down to view a file, leaving the folder then returning positions the window at the top again. This means scrolling down to find that file again.
Work on a project where there are multiple folders of many images and repeat this going back/forth/scrolling a few times. That's when you'd realize how nice it would be to return where you were.
That's probably useful you request for, but I can't fully imagine it - it would be better you posted some screenshots which illustrate your idea, so there's more change Bridge team is going to implement it, while users vote for ;)
