View list of all packages in workspace via eclipse

I am starting development on a new project in an existing workspace. I want to try to organize my source in a similar way to the other projects, and use the same general packages when possible. My problem is, I can't remember what packages have开发者_JS百科 been made already. Therefor I was wondering if there was a way to find a list of all the packages in the current workspace. I have found similar questions about viewing a list of projects in a workspace, but haven't found anything yet on listing packages. If someone could help me out that would be great.

Thanks!
