If you are setting up your classroom in advance, and you'd like to bring in a poll or chat pod to place over a share pod (rather than going to a new layout), you can open, size, position and then hide all your pods in advance. When you then again pull them up from Pod > type (e.g. Chat) they will appear where you "last left them" - avoiding you having to maneuver them around the screen while learners are watching.
