[Zope-dev] find unused objects: hopefully the last misunderstanding... :o)

Well, I simply liked to know if anyone had already done it, so I simply
forgot to add them.

Well, the search seed could be an optional argument w/default value
'index_html'.

Interesting suggestions! Of course, these unfortunately won't handle
the acquisition thing correctly.

To dream a dream:

Consider a tab for folderish objects which allows to search them for
unused scripts/methods/... (after pressing a button because it would
possibly take a while), producing a sortable list of links, with
checkboxes for deletion...

Consider a tab for methods... which allows to parse them and produces
a sortable list of links to the other referenced methods...

Maybe I'll write something like that, but it would be my very first
Zope product.

By the way, new question:
Is this the correct mailing list for such suggestions?
If not, which one is it?
