Or maybe some JS that redirects/reloads on startup?

Why not just have it point to a view that works this out and then
performs an immediate redirect?

Maybe because it had a terrible title? :-)

This leaves me asking, "what did you try"... Did you fail to install a
viewlet? Did you fail to make it have the layout you want? There's not
enough information here to help you. If I ignored the post the first
time, it was probably because of the open-ended question. ;-)
A viewlet can be made to work - as can a bunch of regular actions and
some creative CSS. At the end of the day, this comes down to CSS.

I don't think it'd be appropriate to change the actions machinery for
this. If actions aren't flexible enough for you, you're most likely
going to be able to register a new viewlet, order it properly, and style
it with CSS.
