Window Tracking Averaging

I find often times with lens flares or abrupt changes in lighting, the window tracker in the color page gets sort of temporarily stunned and thrown off for a few frames before finding its footing again. Those few frames it will jump around sporadically. Of course you can select and delete portions of a track and either retrack or manually fix the track. However, I think it could be useful to create a track smoothing feature that averages the track with i.e. 5-10 frames ahead and behind.
