I'll try to make F1 to turn on and F2 to turn off, also a panic button. This was actually in an early-build integrated as you can see in the first picture, but it didn't worked quiet well, so i need to find a better way right now.

That's because of FarDistanceESP has been patched by Valve and that this is more focused on Performance than Quality. The Glow should stutter sometimes.
