title: Gitlab can't open Directory
body: <p>I have to subprojects in my gitlab repository, client and server, but I can't open the server directory, what does the symbol in the screenshot mean? I suppose it means it is a seperate git repository, but I checked the server directory and there was no <code>.git</code> directory in it.</p>
