I'd love to see a UI regarding blinking, where you can adjust the frequency/randomness factor. Maybe sliders, or even the ability to type in numbers, like a minimum and maximum number in milliseconds for each one. So you could do, say, 2000ms-2000ms, so exactly every 2 seconds, the "blink" would occur. Or 500ms-3000ms, so between every .5 and 3 seconds, randomly it would occur. It would be nice to have this available on a per-object basis, as well. For instance, I use the blink functionality not just for my character's eyes, but for the arms when using a mouse/keyboard or a controller. The "blink" animation is simply the arms/hands/fingers being in a slightly different position, so it looks like the character is moving the controller or mouse every so often. Being able to adjust the time factors would be great for things like that, especially if it could be separate from the eye blinking frequency!
