Master slide / whiteboard
It would be useful to have an option similar to Microsoft Powerpoint whereby you can have a master slide for standard content such as company logos. An option may be to have a master "blackboard" which you could adjust to have standard images such as a logo at the top right, or left, etc. This would allow it to be easier to adjust company logos without having to change each slide. It would also need to be necessary to specify if a whiteboard should use the master template, or possibly which template it should use, so that different "blackboards" could have different templates.
