Yehaw!

Man I was so excited to see this beautifully designed app as a solution to my fic woes! Most notably, the digital collation of WIP updates so I don't have to deal with separate files after each new chapter drop. The dev is even releasing new features in the coming weeks that will enable highlighting and notes! (Hopefully page #s too!) Thanks for making this!

(iCloud subscriber tip: put all your EPUBS in a cloud folder so you can access your fics on different devices w/o downloading them multiple times!)
