I wonder if changing the day night cycle to effect different parts of the world at different time. like while half the planet is in day the other half would be night? while not a big change it be kind of neat and just one of those extra little touches.

I dont think dirt should be trashable. it should take up space and you shouldent be able to just get rid of it. small stuff like seeds or something ya compost is a great idea but dirt and tailings i think you should have to deal with finding a spot for it. ¯_(ツ)_/¯

I also think a crouch would be very handy for when your working at different elevations. Dig higher up and then crouch to get that extra little bit of distance down so you can place a block further down is really handy. Or your having a hard time clicking something at a angle below you crouching makes that easier. Just my two cents.
