WiFi-based reminders
What about reminders, that start if connecting a specific WiFi?
I know from other apps, that it's possible for an app to get the name of the WiFi used at a time.
Many of my contexts have their own WiFi-networks - for example if I enter my home and connect the WiFi "Home" and I've set a WiFi-reminder to the context "Home", this reminder shows me the tasks.
(The GPS-based location reminders seem not to work properly on my phone, but also if they did, this idea could be a useful alternative - GPS sucks battery down on most phones, so many people, me included, turn it off from time to time)
