This is the one oddity to me with Apple apps, the seemingly arbitrary landscape option on iPs/iPTs.
Landscape: Mail, Browser, Photos, Music, Calendar
No Landscape mode: Podcasts, Remote, Weather, Reminders
Some landscape modes are clever and really optimize the wider viewing experience like Cal switching from daily to weekly, some are confusing as hell like music switching from a UI with controls to a collage of album covers ...
I had actually wondered when iOS7 was first announced if a landscape Springboard mode was going to be introduced - since going from landscape-to-portrait-to-landscape is a bit funky, though the new task switcher works nicely in landscape (funny that the orientation in the preview “sticks” to the last used orientation...)
OK, enough of that ...
I wish the music app didn't have landscape mode on iphone...or that you could turn it off at least. It's an impractical way of picking music for me. (I have a large Library)
Yeah, I’d prefer just a portrait based view, with maybe some additional controls/up-next preview, etc., in the extra width.
