Siri- make it available off line. Make it so you don't need to activate it without pressing any buttons like simply activate it by saying " hi Siri, or wake up Siri"
Also allow Siri the ability to not only open an app, but close them as well, like " close all applications Siri" or specific applications you have open.
Also allow Siri to change settings such as turn off wifi, Bluetooth etc, oh and basically make more improvements in terms of results, speed etc
Maps- can you make maps offline? If not, then allow it like google does on android mobiles etc.
Toggles- in the notification pull down add varies setting toggles such as wifi, Bluetooth, brightness etc. if not, why not make use of the "search screen" so when you swipe left on the home screen, there is the ability to add certain setting options, as well as the ability to search items on the phone? When you want to search simple type I'm the the settings will fade away, and the searched items will appear.
Side-by side apps: make use of the great ipad screen size by allows side by side apps, just like windows 8 or Samsung does.
Widgets: freshen up the ui by adding widgets and live app icons.
BETTER KEYBOARD: swift key 3 makes the iOS keyboard look and act like 5 year old technology, it's far more advanced and better to use, and I'm really surprised apple fans haven't kicked up more of a storm for how behind apple devices are for keyboard input.
Mail app: allow a delete all mail, I don't want to keep deleting individual mail, I place all important , mail in a separate folder, so allow me to delete all the rest with a single click.
