Yeah, I would like it if the Aim Assist went all the way down into the Bus Pane.Good call.
Also, in X1, the Aim Assist would still be viewable when moving your mouse cursor into the TimeLine, but in X2, it disapears.
It will temproarily appear if you move your mouse cursor up until the Magnifing Glass appears for the Zoom feature. After zooming in this fashion you can move your mouse around the timeline and the Aim Assist will remain viewable, but after moving to the Clips pane then back to the Timeline, it will disapear again.
