Members Directory customization/additions

Hello, I love the Members Directory plugin but I feel like there could be a few more options (at least ones I would like to use).

First, I am wondering if it would be possible to easily customize the CSS layout of the directory plugin, without digging around in members-directory.php.

Also, Is there anyway to add tabbed options to the individual profile pages to show the following:

-Tab showing profile information (like the plugin already does but with its own tab)
-Tab showing Network Sites user is administrator of and/or a member of
-Tab showing Network wide posts and what site it was posted on
-Tab showing Network wide friends

It would be VERY similar to this:

Please let me know if this is possible. I would love to have this for my site.

Thank you!
