The OSX command line tool to open files/directories has a "-n" flag to open in a new window. However, using this flag will cause an existing open project window to be brought to the foreground.
- Start ST2, open a project (say, P1)
- Minimize that project to the taskbar
- subn -n <P2 directory>
Window containing P1 is unminimized before the window for P2 is created.
