Apple should add shortcuts to the siri pop up rather than requiring speech.
Shortcuts seem really great however having to tell siri which one to use, while useful if driving etc, seems slower than just clicking a button if you walk home or something.
Apple should allow 4 or so commonly used shortcuts you have made to appear when you double click the home button to call up siri. At this point the screen is empty until siri starts filling it with text when you talk. I am imaginging a single row of 4 icons similar size to the homescreen icons that you have associated with your 4 top shortcuts that sit at the top of the screen. This way you still have plenty of room to see siri input/ouput text but also gain quick access to launch a shortcut if you are in a hurry.
