I think that the Redstone area of Gameplay should be expanded more to be much more amazing such as having an Automatic Ballista Turret fire at hostile mobs with Arrows that must be supplied and is powered by the mythical, Nether Star and Blocks of Redstone to keep it stable along with a Bow (More things should be added to the recipe. Ballista shoots at ONLY hostile mobs). A Puller, kind of like a Hopper, but a suction rather than a catching and piping system going down. The Puller does just that, pulls items from a container up instead of down allowing for various ways of commonly moving items in a neat and easier automatic fashion. Perhaps a few more items in Minecarts despite not many people actually using them, but perhaps people want a Brewing Stand in a Minecart or a Cauldron to transport water or potions? But these are just a few suggestions that could be useful in some sort of Redstone expansion in a future update that might make things more interesting or in a way, more motivation in wanting to craft these new items and build/experiment with them!
