If you have a cool Applet idea, there's no need to wait, though: Build it yourself in the IFTTT Platform. You can build and publish powerful Applets that work with any of the services on IFTTT for you and other users to turn on.
If you just want to make a cool new Applet for yourself, you already have the power. Head to IFTTT or the app and combine two services into something new.
