Oops, replied to the wrong post. There are lot of Mart.*n's floating

That's your decision to make. There are complications though with
in-module ordering too if additional viewlets are added from outside the

Agreed, this was definately sent to the wrong post. :)
Currently, a viewletmanager does nothing more than iterate over the
viewlets, sort order and filters are optional. The common case however
is an ordered viewletmanager. Grok may want to do something like plone
portlets and create a new flavor of viewlet. For draft purposes, let's
call it a groklet.
grok.order(10) # if missing, raise error or possibily replace with
Appears in template as...myview.pt
<span tal:replace="structure groklet:left_column" />
Note, there is no need to create an additional class for viewletmanager
here, since we are exercising the common case. When custom
viewletmanagers are needed, use viewlets. When dynamic policy and user
permissions are important use, plone portlets.
