I often work with Adobe Photoshop, so sometimes I need to open a downloaded picture in this program. I used Chrome previously and have a habit to drag and drop picture straight from the download bar in the browser to the Photoshop icon on my taskbar in order to open the picture (in Photoshop). Unfortunately, this doesn't work with Opera, once I click on download bar and drag a downloaded picture (or any other file) to an application it doesn't go beyond opera.
