So far this is easier, tad more efficient for me anyway and less windows mess. It could be just me today or my computer running a bit better, not likely, lol, BUT it does seem smoother running in a tab instead of another added window. I was dinging a fair amount more than I usually do.
All I can say is if you want to try it yourself go for it. Obviously you don't HAVE to do it this way but it's easier and better for me so far.
