Last night I got to wonder whether the different panels of information windows might be movable, so you could put what you liked in what order you like ... I don't know if they do that, but it'd seem reasonably easy to implement. At the very least it'd be no harder than setting a customized toolbar is.

I suppose I see the value of RSS, for some applications anyway, but I feel justified in keeping my response somewhat reserved.
