Not for toast messages. I know there is a web browser integrated into the LG Web OS so I didn't know if a specific web address could be input and showed in a PIP or just change the screen and flip back to original programming after a set time. Just a thought since C4 won't let you, to my knowledge, switch to a live view of a camera in response to a triggered event and then return to previous input. I heard that was removed in one of the latest releases.
