The problem with the simple and advanced time-line is that the two UIs present different and incompatible abstractions to the user. For example, imagine that a user has spent countless hours tweaking the volume key-frames for a clip. What, then, happens if they switch to the simple time-line and move the clip's volume slider? Does it flatten the curve? What value does the volume slider display? The easiest solution to this problem is to drop the volume slider from the simple time-line (or at least disable it if key framing is enabled.
