Llama event on manual profile change Can I call an event in Llama on manual profile change?

E.g. Change profile to Develop = when connected to laptop disable screen lock, always on etc.
No, you cannot set up an event to trigger when a Llama profile has changed. Changing a Llama profile is only an action, and unfortunately isn't available as a condition.

There also isn't a condition for Connected to Computer. But there is a Charging or Unplugged condition that you can use to trigger other events. If you are fine with the more broad event of activating a profile when the phone is plugged in (to anything), that's doable.
