presentation/projector mode

Feature summary

Currently if We plug a projector to laptop, we get 4 options (join displays, mirror, main, external) this proposal is 5th option. Additional mode of external display/ projector

That will suit the needs of presentation displays, projectors, and TV with wi-fi display

How would you like it to work

• In that mode overview and app grid is not shown on the presentation display
• It is not connected to the main display by edges (you can't drag windows by accident)
• No notifications on the presentation display
• Playback control on the main display
• No sensitive or personal data on the display
• Main display will work as it usually works
• To open something on the presentation display need to open a file and choose "present"

That extra mode might make be beneficial for presentation, where you don't want to show personal information or interrupt audience (open preview, drug a program by accident, mouse reveals playback control)

Relevant links, screenshots, screencasts etc.

I am not a designer, but it how it can look like
