Does anyone else have the trouble that I do in watching these short animations introducing some feature? I must be slow because I always have to watch them two or three times to figure out what they are trying to show me. I think if they ran at a more leisurely pace I would comprehend them faster. The worst are new editor packages; trying to follow what's going on in a Vim session or an Emacs session with the author flying through the features of his or her new package without commentary is always frustrating to me.
