Externally called files/directories are opened in a a new tab of an instance of Dolphin that already exists. If any of the given URIs are already open in a tab, then those tabs are activated instead of a new tab being opened. If there is no instance then the files/directories are opened in a new window. The newly opened file/directory has its tab activated, and consequently, the window is also activated.
When the user clicks "Open In New Window" or "Detach Tab", the files/directories are opened in a new window.
