I'm not positive this is the correct place for this post, if not please move it to the right place.
I am writing to see if any of the developers has considered implementing Spritz into Calibre? I came across that about a year ago and have been waiting for someone to come up with a Windows e-book program that I could use it with as currently it is only available for certain smart phones. (Ideally at like Amazon to add it to their Kindles, but I'll believe that when I see it!).
If you're not familiar with Spritz, it is a cool program to help you read faster.
Here is the link: Spritz
I hope someone can figure out a way to add this as I would be able to get through books a lot faster!
