The only flaw I can see so far is customising the CSS. A category page calls 5 (!!) CSS files, and I've spent hours in Firebug trying to find out what calls what, and which sheet is over-riding the other.
Using the joom_local.css over-ride isn't ideal, so i've actually emptied every style sheet and put it in joom_local.css.
My view is that 1 long stylesheet is better than 5 short ones. Great work otherwise
Thanks for your feedback! We plan to combine all stylesheets into one compact file for the next release. The joom_local.css file allows your adjustments to persist throughout updates, which might overwrite the default files.
