I have bound gesture lock to a button on my index controller and use it very frequently. If you use index controllers, this is pretty much the only way to quickly and consistently do gestures.
With the new HUD, the gesture lock icon shows up as a nearly monotone icon in a notification box. It's almost impossible to discern whether it is on or off without looking directly at it because there is so little visual difference between the two states, plus the extra visual noise of the notification box.
In the live build, the "unlocked" state is bright green and "locked" state is grey/red, which makes it easy to see the current state of it purely from your peripheral vision. Please change the icon's appearance/behavior to be more similar to the live build.
