I installed the Dolphin File manager when Ubuntu 13.04's file manager stopped supporting expandable folders in the file pane. Sometimes I like to have separate Dolphin instances running in my various Unity work spaces. As it is, I can open an existing Dolphin instance, open the file menu, and select "New Window" to create a new Dolphin instance. I can then move the new Dolphin instance to the appropriate workspace.
I would rather, from appropriate workspace, right click the Dolphin file manager icon in the Unity launcher bar and select an option that says, "New Window". Unfortunately, that option does not exist.
I tried opening a terminal and entering the following commands:
gsettings get com.canonical.Unity.Launcher favorites
cd /usr/share/applications/
gksudo gedit unity://expo-icon
My effort failed; Dolphin is not launched from a *.desktop file. Can someone please tell me how to add a "New Window" option to the Dolphin icon in the Unity launcher?
