I used the duplicate hotkey a ton in 1.3, I would really like that to return 

Seconded. I love the new update in every way, but this is the one thing I miss. Control-C, control-V is somewhat of a workaround but you cant paste to the same exact coordinates which would make life much easier.

Thanks, duly noted! I wasn't aware people used the clone method since copy/paste was introduced, I'll see that it gets re-introduced.
