I would love to see a speed reading feature similar to Amazon Fire's "Word Runner". It uses the RSVP system similar to Spritz reader and Spreeder. This is a great tool and is really effective.

I've never used this but I really like the sound of it.
May be put it in https://logos.uservoice.com/forums/42823-logos-bible-software-8?
Looks like there is an existing proposal in UserVoice:
Rapid Serial Visual Presentation allows for speed reading by presenting a single word at a time and allowing users to adjust the rate at which words are shown (in my own experience, more than doubling reading speed). http://spritzinc.com has a particularly good tool that has been integrated into a number of programs. It would be hugely helpful to be able to read a Logos library this way!
This would be cool, though I'm not sure I'd use it. I've had some stuff like this on my phone before and got bored with it after a while.
