It might serve as an example that can be adapted. If you really need a main menu I suppose you could run a small instance of Docky or AWN (with a main menu applet and nothing else). There's probably a screenlets applet too, although there isn't one in the base pack of applets.
I don't think there's anything like launcher applets yet - maybe we'll see these in the future? It is possible to add functionality to launcher items; there's an explanation for the Home folder icon here: askubuntu. com/questions/ 35024/how- to-add- my-favorite- places- as-a-quicklist- in-my-homes- icon-in- unity
