Did try opening the same view in multiple tabs and they don't stay sync'd. When you change one, the other gets a * by its name, illustrating that it's been changed but it doesn't re-sync.

And cool. I'll do that once I can grab a few screen shots and build a mock up. I guess there would be two features. One that you can do a vertical split rather than a horizontal split and two, that you can take the Visual and Source sub-views into their own tabs and that they stay sync'd. That would allow you to do the dual monitor thing, I think.

Whoops. I stand, somewhat corrected. After posting that, I went and played around a second and found a way to get it to do what I want, although it wasn't as I expected.

If you have two tabs open on the same file, one with source and one with preview if you edit the source view, the preview view does not automatically update. However, if you have one tab with source and the other with the visual/source option open, the visual portion will update if you change the source in the other tab.

I would've edited my previous post but it says I can't edit posts. >>;;

So, while this isn't exactly what I expected, it does do what I need it to do. I'll still probably suggest the vertical split though as a feature request.

Alright. I should get a chance to post them this evening.
