OK, what I can do - to begin with the infrastructure - is to replace
'root_uid' (String) with 'root_uids' (String List) and use a line widget
in the UI to begin with (as in the action portlet)
then getNavigationItems.py will go through all the root uids one by one.
and the portlet will display several trees simultaneously.
this is needed by the way for the default theme (I noticed it yesterday)
that shows a link to both sections and workspaces at the same time.
can you then design a widget that does the multiselection? if none
already exists?
