Excuse me but i was wondering if you could add some new awesome features?

Excuse me but i was wondering if you could add some new awesome features.
Like:
—
Do so you can copy worlds/ Make a duplicate world in the world options. (So that you can copy worlds without needed to go to
%appdata% when you have to copy a world.)
—
The second thing is:
That you can ride wolves.
—
I REALLY hope that you guys at Mojang can ad these features to Minecraft 1.7! That really makes it easier for MANY people.

And, Sorry for puting this under bugs.. There was no other options.
