Hydra, a rendezvous-enabled text editor allowing you to collaborative work on the same document with multiple parties, has been updated to version 1.1.1. The update brings a cool new feature: when you edit a HTML page, Hydra can display a live (!) updating rendered preview.
Very useful for prototyping HTML but even more useful for teaching it interactively: everybody can see and make changes in the same HTML document and everybody can see the results of any editing action immediately. Hope BBEdit adopts this feature soon.
The fast pace in which OS X utilities adopt the new WebCore HTML renderer is amazing. It seems as if in the end there will be no application not making use of it somehow. [via Ben]
