I've had much success with bblean (which you can see a bit of in my edited post below), which you can use to build fancy extensible dock/wharf "menus" like that. You can use icons or text labels, AFAIK. You could in theory make it look all shiny and fancy like the aston shell one, but I don't know if anyone has made such things for the blackbox shells. They are meant to not be glitzy, afterall.
