BTreeFolder Product Released
BTree Folders allow you to store thousands of objects in a single folder without causing a burden for Zope.
This is another of Shane's experiments in Zope architecture. A future version of Zope may incorporate the features provided by this product: the usage of BTrees to store subobjects and the usage of a simple listbox to display the list of objects in browsers.
