Session save/load is a powerful feature for keeping snapshots of your work that can be resumed later on. You can use this to simply save your work as you go, or you can create template sessions that can be quickly switched between for different presentations, templates etc.
Sessions are saved as a special file containing your content and a snapshot of content like web pages that were open at the time of saving. Please note that web browser windows will reload to the latest version of the page when resuming the session.
In a Collab session, you can also change the background to be any image or video, which is saved into the session. So your sessions can have their own unique look and feel when switching between them.
Step through the guide below to understand how to save/load sessions, and change the background in your sessions.
