Oh, I don't know if there is a good reason to add it. At least I can't think of one off the top of my head, because as Ken puts it - "re-start the app"
My reason for asking was that lately I've have been having trouble reconnecting to the Stoker, and it usually ends up taking me about 10 minutes to get reconnected, so this weekend I got everything setup and connected to the Stoker about 3 hours before I was ready to fire it up. And instead of going through trying to reconnect, I left everthing running. When it was time to put the fire on, I thought to myself that it would be nice to just reset the graph. That's when I remembered some posts about key sequences but culdn't remember the details.
