With the new Track Matte Layers option, I seam to be missing something important: when duplicating a layer with a connected Track Matte, the new duplicate still associates to the previous layer's Track Matte Layer. I know this is a feature, but when Splitting the layer the associated layers are no longer stacked and the Track Matte Layer is separate. This is a big shift in UX. I love the Duplicate Layer w/ shared Track Matte, but when Splitting, this is a big distraction. Is there a Pref to solve this or a multiple keystroke that I'm missing?
