There is more than one way. The proper way would probably to be adjust
the security settings on your class in python (filtered_metatypes?). The
easier way is to just to just write an HTMLFile dtml page to overide
manage_main which is what gets called for contents. You can use the
original as inspiration its at /OFS/main.dtml. An advantage of this is
you can add custom stuff to your contents page based on the context of
your product.
