One for the long-term possible things to implement I've been mulling over since I got my iPhone 6.
When I'm in my car and I'm using JRemote, I really actually love the scaled display. It makes it have just a tad larger tap-targets onscreen, which makes it much more convenient than it was on my old iPhone 5 to hit the "next track" button or quickly rate a track (using my windshield holder mount thingy) when I'm wizzing down the road.
Of course, I don't want to normally have everything scaled.
But, I've been thinking... My iPhone knows when I'm hauling ass and probably traveling in a car. What if JRemote could (optionally, since you'll have to request location permissions) sense when I'm going fast, and then scale the display to "big, clumsy mode" rather than have the smaller "fully utilized" display? I imagine it might also be handy for people who use JRemote while bicycling and whatnot as well.
I know there are at least a few podcast player apps that are doing the same thing. I think that'd be a pretty cool little addition.
