how to use tags
Other than being able to do a saved search on tags, is there a way to use them to sort your references? Maybe the feature is not fully developed yet, I would expect it to act something like del.icio.us, where you can click on a tag and bring up all of its references, then be able to click another tag to bring up references with both tags.
I love this approach though from Dan's message in another thread: With the caveat that matching children will appear as belonging to greyed-out parent items, rather than as top-level items.
