Late to the game, but I'm super pumped about M3 and
also the update to the existing Marvin app. I've been using Marvin for 2.5 years and it's the best reader hands-down. (I miss it terribly on my Fire tablet.).
I was worried that focus was primarily on the Gerty app and there woudn't be more Marvin updates. I've been experiencing a glitch when downloading multiple books from Dropbox in 'Get Books'. Very excited to see that addressed in the recent update!
I downloaded Marvin 3 today and it looks just as sleek and intuitive as I've come to love. Looking forward to exploring it more.
