Yes pembquist, that was a portion of my wish also. There currently is a target lock system that puts a box around the icon tag. It is initiated by the player and only the plane directly in front of the target has that box "highlight". I was hoping that part of the wish would not have to be completely re written from scratch, replacing the boxed icon tag with silhouette (but I really don't know if that is more or less complicated for the coader).
Also, even I could imagine that just drawing a single line outline, is a complicated task in itself (maybe not so much for the talented staff here). It is just one of those things that I am wishing that others including HTC could find some benefit from the idea. I don't sweat the specifics, in as much that HTC usually goes the step beyond, if it is inline with his vision for his product (no pun intended).
DaddyAce, I do not have the color blind gene, but have enough sight loss to appreciate anyone's effort to improve this gaming experience for all involved. Especially, if it does not unnecessarily impact others' experience.
