Edit: Jared gave me some guidelines and his modification, I think looks a lot better if you change "font-size property on line 256".
Change it to for example '80%' instead: http://img516.imageshack.us/img516/6353/80perce...
or
'75%': http://img516.imageshack.us/img516/653/75percen...

Thanks, Johannes. Great tip!

If anyone is interested, I made a further modification to this script. Instead of just "prettying up" the page, I also have it rewrite the file names so that the full names are displayed. By default, Apache seems to truncate the file names to the first 20 characters, which is pretty darn annoying on pages like this:

If anyone's interested in this modification, you can grab it from the following site:

The schmoocon link I posted above makes for a good test case if you're curious to see how it works in comparison to the original script.

Mark, thanks for making this possible to begin with. :-)

Quick fix for the "Component not available" error: change lines 176 and 177 to:

tr.addEventListener("mouseover", function() { this.className = 'ruled'; return false; }, false);
tr.addEventListener("mouseout", function() { this.className = ''; return false; }, false);

Under FF 1.5 and GM 0.6.4, this does nothing for me besides just throwing the mysterious error "Component is not available."

I am having problems with FF 1.5 and GM 0.6.4.

Doesn't appear to be functional under Firefox 1.5 beta and/or greasemonkey 0.6.2

I love the look but often get a blank page and have to refresh several times before the directory shows up.

I love the minimalised and elegant look of the new directory views.
