What worries me, is that you need to set font-size in the parameters: these kinds of things should only be set in my template's CSS. Also, there doesn't seem to be a way to switch off the module's own CSS, so i need to override some styles.
Otherwise, good job!
Thank you for the review, it is important to get feedback (good and/or bad) and helps on improving the product.
Although I understand where you are coming from, I don't see a reason for concern as the module is fully skinnable and any CSS property can be overridden. The font sizing has been requested by several users. But here again, nothing prevents anyone to override it. I will add an option to output a 'bare' module in the next iteration of the extension for all hard core stylers out there who want full control over it.
