Until CS6, I would routinely toss in a random vector shape and would then drag it's vector mask thumbnail, in the Layers Panel, to the trashcan icon, which left me with a wonderful color-filled, maskless, vector layer that had a Layers Panel color swatch thumbnail I could easily and oh so quickly double-click to change it's floodfill. Great. Many uses. Loved it.
Not so in CS6, no vector mask thumbnails anymore (yes, due to the update to overall Layers mechanics).
Is a floodfilled layer still possible in CS6?
