Preview / Edit modes
When you are logged in and viewing one of your exhibitions, it can be useful to view it exactly as a visitor will see it, without the edit buttons etc.
By default when you login you will be in 'edit' mode, you can change this at anytime by clicking the 'Eye' symbol top right in the header to switch to 'Preview' mode. The symbol will change to an 'Edit' icon, clicking on that will take you back to 'Edit' mode again.
