My main issue is with the UX - the things that I do most commonly are tricky in Fountain.
My example usecase is: someone mentions (e.g. on twitter) there's a new episode of Preston's TIP podcast and so I want to listen to it.
Currently this requires 8 interactions... Home>Podcasts>Shows>scroll>tap>Episodes>wait(10s)>Play.
I would expect this in 1-2 interactions.
