Better support for different / and /yacs pages

In order to have separate tabs for / and /yacs I had to hack skins/page.php with something like

function top_focus($prefix='tab_') {
        global $context;

        // not sure there is a focus
        $output = NULL;

        // alter 'home' logic for site with unique page at slash
        if($_SERVER['REQUEST_URI'] 
 '/' || $_SERVER['REQUEST_URI'] 

    '/index.php')
            $output = 'slash';
        // focus on home tab
        elseif($context['skin_variant'] == 'home')
            $output = 'home';

and the put the following in my skin template.php

Page::tabs(FALSE, FALSE, array('/' => array(NULL, '/', NULL, 'slash'),
    '/technotes' => array(NULL, '/technotes', NULL, 'home')));

Also, I tweaked the site slogan in my skin to note display at /.

It seemed like a lot of effort to figure out these tweaks, could yacs support a better way?

Also, I notice that http://www.yetanothercommunitysystem.com and http://www.yetanothercommunitysystem.com/yacs both "activate" the YACS tab (because they're both considered "home" by top_focus), but those two have different content, kind of confusing. I didn't want that behavior.

I'm not needing a fancy subsystem here, just a little cleanup in the tabbing and skinning stuff to distinguish / and /yacs.

Btw, I use /technotes instead of /yacs, "mv yacs technotes", if you will.

Oh yeah, the sites at www.morison.biz . See how that page is different than www.morison.biz/technotes .
