It's a bit cumbersome when viewing one's site to scroll up to the top to get at the dashboard buttons. Any chance of those buttons can be made to stay accessible while viewing your blog?
Also, my theme (Quentin, my blog is maximilion.wordpress.com) scrolls the right-hand sidebar with the texts. After a while (already, really) the texts become long and a viewer will find him- or herself scrolling a long way up to the top where the useful widgets are. I don't see why anyone would want it that way. Any way you could make the sidebar scroll separately so it stays visible?
Edit: Or are there themes who does this already? Been thinking of switching to Ocadia.
