Testing on android shows a huge bag of poop fail.

We actually want different behavior based on the environment

We should have a checkbox that is required to be clicked to "Edit when in Slideshow View"

Things we need to worry about interactions

Swipe Events (Left, Right, Down)

When on Slideshow view

Left = Previous Slide, Right = Next Slide, Down = End Slideshow View

Click Events (Left, Right and Mouse Wheel)

When on Slideshow view

Left = Next Slide
Right = Previous Slide
Mouse Wheel up = Previous Slide
Mouse Wheel down = Next Slide

Keyboard Events (Cursor keys) -- This is when it gets tricky because you can actually Edit slides and to do that you need cursor key access..

When on Slideshow view

Left = Next Slide
Right = Previous Slide
Mouse Wheel up = Previous Slide
Mouse Wheel down = Next Slide

Caret Focus on Ace Editor = all keys still work as normal (except Escape).

All of these potential interactions need documenting in the README

I still have swipe left to implement, should be easier now we have a setting for editing
