I just started using this theme and I do consider it the best of wordpress.com when it comes to ballance between clarity, functionality and aesthetics. But personally I do have one disappointment with this theme: there is no HOME hyperlink when you click the header.
The header has an option to be "equipped" with his own text option - which is the blog title. But I personally prefer my own fonts and certainly don't want the dark glassy background behind the title. So I unchecked the text option and had the title of my blog directly into the image header.
That is why I consider that hyperlinking the header with HOME would be an excellent tweak (would make this theme perfect as far as I am concerned).
Since this is a suggestion, I am not sure how a link to my blog is necessary, but just in case: http://subsoare.wordpress.com/
The blog I need help with is subsoare.wordpress.com.
