Not sure how many people here do use Photoshop, probably not many, but I still do. As such I find it convenient to be able to select an image in dt and have it open in PS, bypassing the need to navigate through piles of folder to find the image and open it.
As of now this strictly opens the selected image (does not export, so your dt edits will NOT carry over. I do hope to add that functionality soon though).
When selecting multiple RAW files only the first one will be opened, however, selecting multiple JPG or TIF they will all open as separate images in PS.
RAW files will open in ACR within PS.
