The one feature I wanted in iOS 11 when they announced it 11 months ago... iCloud Messages. It's in the recent betas, hopefully they don't yank it again like they have previously.
Music App
- Ability to turn viewing of cloud purchases on or off. It's a nice feature, but not nice to have forced on you. I only want to see local music on my device. I don't like having to use the "Downloaded" tab to do that, as its not persistent. Close the app or restart your device, you have to do it again.
-Better syncing of playcounts. One reason why I only use local music is because I rely on playcounts/last played date quite a bit. If you have automatic downloads turned on, and buy a song on your iPhone and listen to it, your computer may have already downloaded the song automatically. When you sync your phone, the playcount data is not reflected in your iTunes library. The same goes for redownloading a purchased song on your device that is already in your iTunes library. As far as I know, the only way to get playcounts to sync is to download to only one device, then sync and either put the song from iTunes on the phone, or use the "Transfer purchases" option when syncing if the song was downloaded to the device first. For this reason, I don't use cloud music or automatic downloads.
-Better cloud services for music. iTunes Match wreaked havoc on my library when it first came out in 2011. If you don't care about metadata, playcounts, smart playlists, etc, then I suppose its fine. If you have a music library you've meticulously built only to see iTunes Match wipe playcounts, playlists, alter your metadata, etc.... it stunk. Since then, I've been afraid to touch iCloud Music Library or iTunes Match again. I've heard they still aren't compatible with smart playlists that reference other playlists. These functions are what made iTunes so great.
-Playlists that I don't choose to sync are on my device anyways. I utilize smart playlists to separate certain types of media for convenience. For instance, if I have a playlist called "Audiobooks" that contains all of my audiobooks, and I choose to sync all of my audiobooks to my iPhone, that playlist will sync over even though nowhere in my iPhone sync settings is that playlist selected. So I have an entry on my iPhone for this playlist, and even worse, since Audiobooks are now in the iBooks app, the playlist appears empty on my iPhone.
-Editing playlists on the go sometimes results in two playlists in iTunes. If I have a playlist in iTunes and my iPhone called "Classic Rock", and edit that playlist on the go, sometimes, when I sync back with iTunes, I'll end up with "Classic Rock" and "Classic Rock 1". So then I have to clean up that mess.
-Syncing still sucks in general. Every time I connect my iPhone to my Mac, I get the "iTunes has found purchased items..." message. I always choose to sync them over, but it never tells me what these items are, and I get the message every time.
Random
-The Settings app needs trimmed down and streamlined.
-In the app closer screen (to force-close apps), there needs to be a "Close All" button. There's plenty of room.
-Would like an ability to delete messages on my Apple Watch from my phone.
-The Notes app is great, but the workflow for scanning documents leaves a lot to be desired.
