Spaces Question

It's not just Safari, you can have multiple windows for just about every OS X app.

I haven't personally used Spaces, but I have talked with some developers and I think I remember them saying this was the case. I would expect so, because every other desktop virtualization software package does this. In VirtueDesktops (R.I.P.), which is what I use now, it does jump to the desktop that app is on if you click on the dock icon. However, if you have that app's windows spread across multiple desktops, as I often do with FireFox, clicking on the app icon does NOT change the desktop. It focuses the app, so you get that app's menu bar, but it doesn't switch desktops since there's really no logical way to determine which one it should go to.

Why would you want to have multiple app windows on different desktops? Especially with a browser, you might want to split up your web sites depending on what type of work you're doing on each desktop.
