I'd like to try this as an option in firefox's reader mode as that's the format in which I read most long texts. This did on the surface feel like it is a help for me, in particular not so much the reading speed but the 'pull' of the words meant I was less likely to get distracted halfway through a paragraph and tab away. (Yes, I suspect I may have undiagnosed adhd).
