Hidden Features of Revit 2009

In previous years, I've really enjoyed ferretting out those "hidden" features or behaviors of Revit in each new release...This year, I've been poking and prodding - but I've only managed to turn up one thing which I would call a "Hidden Feature".Revit URL SupportI noticed as you mouse over files in the new Startup Screen, in the bottom left corner you see not the filename - but a URL:This made me think - does this mean that Revit supports URLs for files now? That might be interesting...So I tried it - Using "File + Open", I typed in a URL of a Revit File I posted on a website, i.e.:http://jennmason.com/RevitTest.rvtAnd sure enough - Revit automatically downloaded the file and opened it.Where did it put it locally? It currently is put in your %TEMP% folder (a previous build was putting it in "My Documents" - I'm not sure of my preference).What does this all mean? I'm not entirely sure, but as models proliferate over the web (or content - my presumption is that you can load a family this way as well) - that Revit being able to open any URL (HTTP, FILE, FTP, etc) - presents some interesting future opportuntities....Another interesting quirk - I notice that when you mouse-over the "New" button, it gives you a URL of:file:///X:/NewProject.startand the Open option gives you file:///X:/OpenProject.start.I haven't delved into what's going on here... Is this some kind of HTML application that we're actually in? What happens if you actually have an X: drive?Anyway - this hidden feature seems to inspire as many questions as answers... Have you discovered any "hidden features"? Drop a comment here and let people know!-Matt
