This applies to the RC version of OS X. As far as I know, you cannot do this in the Public Beta.
In Project Builder, when you choose "New Project..." from the file menu, you have many projects to choose from, Cocoa, Carbon, etc. I recently found a way to create new pre-built projects and include them in this area. I'm not exactly sure how useful this would be, but I thought it was worth mentioning. Here's a step by step instructions on creating a pre-built project:
1. Create a new project in project builder, and edit it any way you like.
2. In the Developer folder, go to a folder called "ProjectBuilder Extras" then to "Project Templates" (You will probably have to gain root access privileges before you can write to this folder; go
here to learn how to do that.)
3. Place your project inside of the "Application" folder (or create a new folder) in the "Project Templates".
4. Go to Project Builder, choose "New Project..." from the file menu. Your new project should appear in the list.
I used this to create some pre-built OpenGL apps, and it works great. Saves me a lot of time without having to setup the OpenGL stuff every time. Hope some of you find it as useful. Oh yes, if you didn't notice, you can also place frameworks, and some other stuff in there too. Pretty cool.
