This one's simple. I have no idea if those are already being planned/ developed, but as versaitle as FaceRig is, it needs more emotions. I'm going to list examples of usage, how the face is shaped as emoticon (and should be in FaceRig) and some other details.

1). I would love to make a YouTube channel in the future and do FaceRig reactions on horror games. But I realized it lacks a fear emotion. Jaw dropped, mouth shaped like a D: face, eyebrows raised/ inner brow raised.

2). Anger. Oh how not wonderful it is to suprise someone with FaceRig, and he tells you to uncover your face because you're a coward. And now you're angry because you've well-spent 10€ on this software. Typical >:( face, Inner brows down, exterior brows up. Mouth eventually shows teeth.

3). Pressed lips/ eyes. A jumpscare appears and you shut down your eyes/ You are frustrated and press your lips. For the eyes, they should look like this: >.<, lips should be rolled inside when pressing them. Do not confuse with normally closed eyes, where the pressure is lower.

4). You talk to your girlfriend for the first time with FaceRig when suddendly she wants to break up, ignoring the application. You show sadness. <:( face, Inner eyebrows up, exterior brows neutral. Mouth downwards.

5). Sturgeon Face. Who does not know the "NOT BAD" meme that includes Obama making a sturgeon face? :C face, bottom lip over the upper lip.

6). As a goodbye, you give your new girlfiend an air kiss. No idea how to make a kissing emoticon, but lips are formed as a circle, jaw and mouth remain closed.

7). Shrugging. In my opinion, FaceRig should additionally detect the shoulders of a person. If the head sinks and the shoulders rise, the avatar should shrug.

I do know that FaceRig is in beta and thus not complete. This is a suggestion and not a guideline, feel free to include (or exclude at the cost of software rating) the given expressions.
