3d Scene Camera Tracker Symbol Improvement

For my most use cases the Camera Tracking is working very well. But I have a small simple idea to improve it and did some rough sketch for it. The Bullseye is doing a bad job, when my tracking data isn´t that good... the circle might be a nice handy interface for recognizing but i could be much better and faster to handle when it has a crosshair extension. Two lines showing the exact vanishing points - maybe a third one for the z aixs. (the data already exist for showin the circle..) Long text - one image. I was trying to locate the Bullseye in the AE program folder by myself... but i can´t find it and i am too busy doing other stuff. What do you think about my suggestion.....? can´t be that hard to update
