However, Ive already got a pretty deep workflow with VCA's and surfaces that will be hard to give up.

I kind of feel the same as Lynn on this.
I have my large templates that I'm happy with and I already have shortcuts and ways to zoom around the tracks quickly and spill them out.
Its interesting to see what others think, hopefully I'll be converted to folder tracks and inspired when they appear.
ARA would be great for me in Post too using RX and I'd love to see an expansion of clip fx to include third party plugins.
These are things I could actually use daily.
I just feel I don't 'need' folder tracks that much.
