Thanks for the feedback, that's a really good idea! I'll try to roll it out shortly!
Also, swiping left to get back to the first slide puts me back in the editor (I went too far), and then hitting slideshow puts me back where I started so I have to swipe left again.
The swipe left on first slide is a feature though, its to help mobile users get back to the editor easily.
Maybe display speaker notes by default if the screen is in portrait mode?
I'll have a think on this tonight and I'm sure we can do a tablet speaker notes mode.
I just want to see the speaker notes while looking at the slides.
