If IdeaJam asks the community new ideas for improving Lotus Notes, RedTurtle Technology answer! 

Here is what was proposed by us recently.

It is the second time in a couple of days that I am asked why in some pages there is no link to the @@manage-portlets view. In both cases the archetypes missing the link (and the view) where inheriting from a very basic object.

After a small research I found that this view is registered for the interface plone.portlets.interfaces.ILocalPortletAssignable.

Making the object interface inherit from this interface solved the problem.
