Run the Presentation View in a new Browser Window or Tab #213
Description
When running a live presentation of an event, the list of items is no longer visible and all activities within cSpot will be visible in the presentation. Similar to PowerPoint or OpenOffice, it should be possible to control the actual presentation screen from the original list of event items screen in order to better know which slide comes next.
For that purpose, the presentation should run in another tab/window of the browser, which then can be used to be projected onto the big screen.
By default, projectors are usually attached to Windows (or iOS?) in order to mirror the local screen. Instead, the OS should be configured to extend the desktop to the projector so that you in essence have 2 Monitors.
Once that is done, the Presentation Tab or Window can be dragged onto the desktop of the second screen (i.e the projector) and then turned into fullscreen mode (F11 in Windows).
