There is often a need to receive feedback from someone for a thing that you did. What better way to receive this feedback from everyone else who uses the engine?
For example, a HUD that you think needs improvement but not sure where. Or a level where the lighting is off but you can't exactly figure out what is wrong.
We have #1054845120236757103, yeah, but that is more of a show-off thing, right? That is what prompted me to make this post, hope you see what I mean.
