I'm new to the forums, so hope I got this in the right thread. Anyway, my question is the following: I know it's possible to choose which applications that'll start on login in OS X, but is it possible to make an application launch when an other application is launched? For example; I have an app called "I Love Stars", and it makes it possible to rate songs in the menubar while they're playing. Very handy app, but it apparently won't start simultaneously as iTunes, and neither seem to have the option in the preferences to do so, so I have to make sure it is on the "start on login"-list. It would be much better to have it start when launching iTunes. That way it's not in the background using resources while not using iTunes (maybe not much of the CPU, but still). And also, Is it possible to do the kind of the opposite?: Make an app quit when you quit another one. Thanks in advance.
