There are bugs with Game Pad mode control binding. I normally play with the Down Dpad set to the "Interact" and A is just for jump (so I can jump even if there are 'usable' things around). However, when I go into the house editor I cant select anything. It still says to press A to select but all I do is jump. If I try Down on Dpad nothing happens.
Also, a separate issue: There is no gamepad bind option for "hold" such as Holding Down DPad + right stick to zoom camera. That feature works in default mode but cant be done if that button was bound to something else for tap mode.
