I agree—haven't noticed a significant difference between the two versions. I wouldn't consider myself a power user, so perhaps there's more to it for advanced users. Still, a great utility.
I am writing a lot of markdown and just tried the trial - it's great. I love especially it's Leanpub support. I would love to have more information on the grammar addon (since I am from Germany) - not sure what's included.
Apart from that, I hope to see mobi and epub export would be enabled as well, which would help greatly to publish ebooks. In the case of Amazon/Mobi, it's "just" a subset of HTML: https://kdp.amazon.com/help/topi...
