One thing I noticed was that when moving the time lines, the start, end, fade in and out points, that sometimes it's not always apparent if I was clicking in the right point to pull the line..causing me to miss and move the timeline frame marker or grabbing the whole cue clip..
I was wondering if there could be a visual CUE, a mouse over or mouse click cursor cue that tells you that are in the right place to move that edge or triangle..
maybe just inverting the mouse cursor color when you click in the right area..or hover on the right area..
or better yet, a highlight over the cue when the mouse is over the proper pixels that control the movement.. similar to the highlight you see on a Windows desktop icon..
