Thank you very much! That took 2 seconds to integrate. Awesome.
As for the lack of nav menus in the first place, not everyone wants to spit into the wind that is standardization. I wanted to integrate P2 into my pre-existing theme (I have a multi-site installation) and got everything modified except for the nav menu.
I guess if you're doing heavy theme customization, you should be able to add in the right code for page navigation. I hack things to pieces and make it work, but I've never actually written my own php code.
Why not make it a checkbox option or something? The theme options seem very minimal... it's a very powerful tool, but it could really have some more theme options.
Ultimately, I used the "Page Links To" plugin to create navbar pages as if the P2 installation was actually a page of my main site. Worked wonderfully... especially if you want to add P2 capabilities to an existing site.
See thecarrfamily.org/chat for the modified version of P2. Then "Page Links To" redirects all of the P2 navbar items to the main site's individual pages.
You'd need a multi-site installation and a pretty heft amount of hacking know-how but the end solution worked out perfectly. I'll be doing this for all of my P2 installations from now on. Thanks again, choibc!!
