Alfresco pallets

I installed Alfresco Community 4 a few days ago. I am using Share.

I am wondering if I can have multiple document libraries on the same site. The thing is, when I create a new site, I have a link to the document library in the top navigation bar. Then if I go to "customize the site" I can add a calendar, wiki, etc. To the top navigation bar, but I'd like to have a second document library, not any of them.

The end result will be Doc Library 1 and Doc Library 2 in the top navigation bar.

Then, I think this is more advanced, but I would like to create a site template, so that when I create a new site, I automatically have a site with two document libraries in the top navigation bar.

I know that changes can be made to the Share app and functionality by modifying or creating XML files in the webapp. If someone can point me to the correct steps and files to create or mofify, that would be great.

Hopefully I don't need to install Eclipse, create and compile a WAR file, etc. as I have never done that.

Also I read that SubSites is not supported in Alfresco Share, but I don't know if the second document library is considered a child library. Perhaps there is an XML file where I can specify an Alfresco site type template instead of creating a site with LIbrary, Calendar, Wiki documents, etc. Just create a site with two document libraries :)

Thank. Regards.
