I have three iPhoto libraries. I hop between them using "iPhoto Library Manager". But I find that it is kind of an inconvenience to open the launcher, choose the library I want and then launch iPhoto every time. Is it possible to duplicate "iPhoto.app" and have "iPhoto.app", "iPhoto2.app", and "iPhoto3.app". Then take my other 2 libraries and in the "Get Info" pane, tell them to open with "iPhoto2" and "iPhoto3"? Is this possible, or is just duplicating the "iPhoto.app" not enough? Of course, with each iLife/iPhoto update, I'd have to duplicate "iPhoto.app" again, which isn't a big deal. This way I can have the three icons in my dock for each of my three libraries. Comments?
