+ HomeKit support
+ Lock screen support (activating scenes and such)
+ better activity logging like a transaction log of which scenes were activated, what rules were run and what activated them (LCD, rule, web, app (which one), IFTTT, etc). This will make it a lot easier to figure out why something happened or didn't when it was/wasn't expected and for efficient automation configuration.
Otherwise the app is pretty good. I use it all the time, mostly to activate scenes and control devices.
