I would love to be able to arrange the order of the Dashboard exactly how I see it. See video: http://somup.com/cb11XoVhpv
I found out (after I recorded the video) that I can add some to favourites, but the downside to that workaround is that the most recent one will always be at the top. Having more than 10 websites in a dashboard would mean that you really have to think really well before you act. Being able to arrange them either by a kind of drag & drop or any other easy way would be better IMO.
