This app has completely revolutionized line memorization for me. I love graduating through the stages of listening to every line, then gap-line for my lines, then finally just gaps for my lines. My turnaround time for being off book is absolutely faster, especially in situations where I have a lot to learn in a short time.
One UX issue utterly baffles me, however. There is a critical menu that you will bring up often during playback that allows you to control gaps, looping, etc. The developer has decided to make that menu animate SOOOOOO SLLLLOOOOWWWLLLLYY. It is an annoying impediment to productivity. There is absolutely no reason that menu slide should take more than 250ms. I think right now its 1500ms with the bounce.
PLEASE bring that duration down to 250ms and lose the bounce. The bounce effect is GREAT for folksy tutorial overlays and games, but it has no place in a productivity app like this.
Other than that, fantastic work!!!
