Viewlets kinda suck, to be honest. They are useful for certain use 
cases, but as a general way to build composite UIs, they suffer from 
some limitations.

The way Plone solves this is to have a viewlet manager that consults a 
persistent (site-local) registry on (a) which viewlets to hide and (b) 
in which order to show the remaining viewlets. There's a GUI to hide and 
re-order things (@@manage-viewlets). This solves a few problems, but 
realistically, it's still not great.
