fixed your issues - please try it one more time and tell me what you think. I enabled the outlines, and added 12.5 degrees of turn radius . I hope that makes it feel better.
the outlines helps lots. But you need to divide the mouse delta when you are in zoom by 10. It is too sensitive and it close to impossible to aim.
There is another issue, when you zoom with the second button the zoom goes to some strange place, not to where the current "red spot" is.
It is starting to look interesting!
