These are the types of features a novice app developer might implement in an afternoon after watching a tutorial video on youtube. A company as huge as Twitter selling this as a subscription seems ridiculous to me. I don't use Twitter much, but IIRC aren't there a bunch of third party apps that have power user features like this already?
