Ability to "watch" and index folders that are user selectable: If Lightroom could have the ability in the preferences to "watch" certain folders and automatically add image files to the LR catalog like Picasa does (minus any exact duplicate image files), this would be an extremely helpful feature. I use Picasa specifically to find image & video files that have either been moved, misplaced, or forgotten on old hard drives/thumb drives. This feature would be turned off by default as it would obviously take up more computer resources & the user wouldn't want this on while working on images. But something you can turn on & let it index while not working in the catalog, i.e. overnight.
