I have compiled a list of all the non implemented autoplay features which in my humble opinion cut out meaningless clicking without reducing meaningful decisions. Feel free to suggest more, as I may have missed some. Before criticizing these autoplays, keep in mind that using autoplay is always a choice and can be turned on or off depending upon the board. Of course, these all have varying importance, and I understand that this is pretty low(if even) on stef's priority list. I mostly just wanted to consolidate all the missing autoplay threads.
