If I double click on a picture in thumbnail mode Photoshop is openend with the picture.
It would be nice if I could change this behavior in the settings to do other things. One option I like would be to view the image in full-screen like it you push the space-button on keyboard.
How often I didn´t think about the fact that Bridge do something other than most other programs on this genre (like ACDSee) do and bam Photoshop is loading.. ;-)
