[Plugin: BuddyPress Groups Extras] Change display options for extra pages

I’ve added a few pages to a group I have in buddypress, and I want the group description and pages menu to show up when viewers are looking at the group home page, and NOT display the content of the first page. When they click on a page in the nav menu, THEN I want the content of that page to show up, but without the group description above it, just a link “Back to group.” So they don’t have to keep scrolling down to get past the same info they’ve already seen over and over (ie group description, which doesn’t change).

I’ve poked around the plugin files, but I’m not exactly sure how to tell the page to check whether the URL is simply http://domain.com/groups/groupname/gpages/, or whether it is http://domain.com/groups/groupname/gpages/pagename. I’d appreciate any advice, I think this is a fabulously useful plugin and would like more control over layout.

Thanks in advance.
