I love vegas and it has so many great things about it that keeps me using it. There are many little things that exist in other NLEs like Adobe Premiere, like nested sequences and smart bins that just adds awesome functionality to the app. Having to import .VEG files back into the timelines is really not the most intuitive way to nest sequences, I would prefer to have tabs and for each tab created a "sequence" file is created in the bins and you can just move these into which ever sequence you chose to make your main.  and linking with AE, wink.
