This completely confounds me.
We are an indie game dev company producing multiplayer QFG style games.
Fair enough.
This technology allows you to bind websites more closely together as well.
Every website you load in a window on your website becomes part of your website 
Why would anyone need that? It wouldn't "become part of your website" because it's another website, you know what I mean?
In the latest versions of firefox you can increase and decrease your window resolution by pressing CTRL- and CTRL+
Also you'll notice if you drag one of the windows over the edge of the screen and drop it the scrollbars size increase, allowing you to open multiple windows at bigger resolution.
Scrolling is in no way a step up from clicking a tab. Tabs become smaller when more pages are open for instance so you get great overview, in this case, you can only get an overview of three pages at a time.
It's similar to a frameset but it has enhanced features such as complete drag and drop capability, Minimizing/Maximizing, Internal browser "still have to add" Makes it where you can browse to your own choice of websites and is possible to open an unlimited amount.
And I'm working on adding more web based tools which are capable of editing images,text file sub systems, ftp capability etc..
I guess the last two functions would be a text editor and some kind of ftp client? Why would you make a less functional desktop, with a browser, inside a browser? people already have operating systems for this stuff.
I am baffled.
