Could you explain what you mean by a hot-key to select the barks? I think, regarding the barks, there's a huge setback. People don't have the sound of the bark and don't know how to record it. But you gave me an idea. I could have some types of barks predefined and people could choose the one that is most likely to be their dog's. What do you think?
