[Zope-CMF] Customizing actions in folder contents view (CMFMember trunk)

[Jeff Kowalczyk]

As a followup question to how to access the folder contents view in
CMFMember trunk/ Plone 2.1 SVN Bundle:

My user-administrators will need a few batch actions on a user base of
under 200 users. Typical batch operations might be be assigning a metadata
date field (effective or expiry date), and assigning a value to a field
added with the schema editor, or batch assigning a keyword, etc.

I was considering customizing the folder contents template at that
location to provide them as button actions. Or making a separate template
calling product code, if that would be easier or less intrusive to the UI.

Has anyone implemented this yet, and/or be willing to share any
suggestions on how to do it?
