I see the enable/disable presentation mode in settings. However, when teaching/presenting, i often switch to playing back videos or showing live demos with the camera. right now my process is:

1. exit pdf by tapping '<-'
2. pull out menu options
3. tap the settings icon
4. tap casting and presenting
5. tap enable <then, select the video/camera app, play video, and switch back to papyrus>
6. tap enable
7. close settings
8. tap to select pdf

This is way better than what i was doing before i knew about the enable/disable presenter mode option (quit squid, disconnect display, reconnect display, show video, etc) but it gets tedious when i do it every few minutes, and it would be really nice if the option were right there in the casting button next to start/stop presentation option that shows or hides the squid splash screen

Thanks!!
