While I don’t believe the ST app should be used for a remote control, hooking into iOS 9’s universal search to pull up devices/smart apps would be super useful.
Searching for a device using Spotlight and being taken directly to it would be amazing.
Deep links could go beyond Spotlight too as apps like Launch Center Pro use them.
I don’t know how you hook into these features from a code standpoint, but any of this on the road map?
