I’m so excited for this upgrade.
What features are you most excited for?
fade editing 
I know it’s not much but i wasted so many hours over the years adjusting a region and changing the fade accordingly !
… hopefully fade window is better too ? anyway these kind of little things really. The rest is nice but yeah something faster, more fluid more reliable.
Coming from Nuendo 10, I’d say the new phase coherent free warp and most definitely the export queue, which is fantastic.
