Now this is one for the cool books. Kinda start to wonder why no one thought of it already.

Ok as you can see by the screen shot above you get the two screens one for firefox and on for  ie. Now this isnt any great feat, but what is cool is that you click the edit button and it automatically loads the linked CSS file and you can start editing it live in the side bar. While your typing the pages to the side update to reflect the changes. I tried to fix a problem I had with my header graphic with Ie being one pixel out of place. And I could see the effects of what I was doing instantly. It was great. There was a noticeable flicker when firefox refreshed its display while the IE window dealt with it alot better. But thats what you would expect in a Micro$oft environment.

Two things I would like to see in this software.

1. Ftp connections which automatically save/upload the CSS file to the right directory (based off the link tag).
2. Dual scrolling. Ie when you scroll the top window the bottom window follows suit. so matching the views can be easy.
3. Changeable layouts. This might (hoping) become available as docking is pretty well supported in .NET. So that you could have a verticle layout for "skinny sites" and horozontal for ….well "fat" sites. 

Now this does require the .NET 2 framework which if you havent already installed it, its a 20MBish download then another 6MB for the app itself. But seriously its worth it. I cant wait to see what further development on this application will yeild.

So big ups to the guys at www.sitevista.com  (theres the free plug). This could be one of those tools I have in the quicklaunch. lol for me thats when an app is really usefull . Go try it out for a bit of a play.
