That was the biggest frustration for me, you can make some kind of semi trim window but it looks really strange having multiple previewwindows in some kind of timeline beside eachother. you also see this layout in the cheap nle's like pinnacle studio or magix videodeluxe as they also use just one videowindow.
For me a second "full" trimwindow is a must for easy and fast editing.

Why? To me it's just wasted space. When I'm in the trimmer, the screen shows me the trimmer. When I'm on the timeline, the screen shows me the timeline. When I'm in the Explorer windows, I can play things there as well. One screen, no muss, no fuss, no wasted space for a second view window.

I can remember seeing this thread about 5 months ago, wondering if I would ever be won over by Vegas from my Pro 2.0. Wow. What a difference 5 months has made. I find myself starting Vegas as my first choice all the time, now. My first feelings were that the program wasn't sophisticated enough.... seemed like something was missing. But everything seems to be there, and easier to use. In comparison, Pro 2.0 seems cumbersome and bloated.

I do like the ability to nest sequences in Pro 2.0, but haven't figured out any ability to do that in Vegas, but other than that, I think Vegas is working out real well.

It's not quite the exact same thing but Vegas will let you next an entire project on a new timeline. You can create a few projects and then just drag the projects onto a new timeline for final assembly.

You do know you can move & resize that window, right? :)

If you read my reply completely you will see I was trying to make a point by refering to the Vegas audio background.
