I would love to see a small feature that would save me and my co-workers a ton of time. When duplicating a layer, there is a drop down menu to duplicate the layer to a new document or other open documents. One feature missing is an option to "duplicate layer to all open files". This would help me and my team tremendously as we work from a master photoshop file to create anywhere from 5-500 files with different photos/colors, etc. Sometimes there is a change to a common element on all the files after they have been built. We make the change to the master file and then have to duplicate that change to all the files that are already built. Having this "duplicate to all open documents" feature would save a lot of time over having to select each file individually.
