cool. small peeve though, the side panel refreshes via fade-in every time i nav anywhere, if you're redrawing the whole thing, at least disable the fade-in so it's less distracting.
To the coders: Nice job on using multiple URLs to allow pages to be viewed without JS enabled. Having to reload each page when it is requested is not trendy, but it's nice to know Mailpile will work on locked-down browsers. Kudos!
