I used a variation on the idea that David posted above, to limit the display to only show the “titles”, “filed under stuff”, and the “comment info line”. This definitely improves the readability of a parent category, and maybe you can extend this for other php variables.
Where David mentions the test for the lack of a post value ($p) to trigger the display of a title, I used the same type of test to not display $the_content variable. If you click on the title you get the whole post. Find this DIV in the index.php file . . .
<div class=”storycontent”>
<?php the_content(); ?>
</div>
replace it with this . . .
<div class=”storycontent”>
<?php if($p != ”) {the_content();} ?>
</div>
This will prevent the content of a post from displaying until you actually click on a post title to read it further. Its not exactly what you want, but its close.
