A toggle between the new / legacy controls, or some more customization would be fantastic — but I actually enjoy the new controls and found them more streamlined than before. People I've watched play the game also echo that sentiment.
Viewing post in How to return the old controls in 0.9.0???
the controls are more "streamlined" in the way an iphone is more "streamlined" than an android. Now I have to wait to do many things I could do in an instant as long as I held one key. Some of the changes are good though, like interacting with heavy objects, since the ambiguity of what you're doing until you start moving it has been taken away.
