qSiloGroup: Looks Handy
Quintagroup's new product qSiloGroup, looks like a handy little tool. It lets you change the name of an item in the navigation tree without changing its title, and to show or hide specific items in the navigation tree.
Plone 3.0 has this latter feature, but qSiloGroup may well be useful to Plone 2.1 and 2.5 users who want a little more control over how things appear in navigation.
Disclaimer: I haven't looked at the code yet, nor have I tested the product in production.
