(Please excuse the lateness, I had appointments this morning.)
1/Rearrange your Share Pane — iOS 8 introduced Share Pane, which enables sharing for specific apps. This is the screen you get when you tap the share icon (the portrait orientation rectangle with an up-arrow in it). You can actually rearrange the layout so the options you tend to use come up first: tap the icon, hold your finger on it, drag. The other way is to tap More and rag the slider-drawer icon things up and down (to sort the order).
2/ Family Sharing — The previous icloud default mode was Family Tearing (its hair out), but now, if you have two or more iCloud accounts in your family, you can still share items purchased on one with the other. You first need to decide who will have the “main” iCloud account – I’d pick the person with the biggest bank account and/or who does the most online iTunes purchasing.
That person: tap Settings, iCloud, then tap ‘Set Up Family Sharing.’ (The other users don’t need to do this). Type in your partner’s iCloud email address, follow the prompts, and they’re added as a family member under your iCloud account.
Once that’s done, you and your husband will be sharing apps, videos and music you’ve bought from iTunes and the App Store, but you’ll have your own contacts, your own Safari bookmarks and be able to track each other (or not, if you choose) using Find My Friends. [I’m not sure if this works with non-iCloud email addresses, but in my tests, it doesn’t.]
3/ Hide App Store purchases — Choose the Updates menu, then tap Purchased. If you have Family Sharing enabled, choose “My Purchases,” and downloaded applications — both free and paid — are listed. These can be sorted by “All” or those “Not on This iPhone.”
Simply swipe an app to the right to display the red HIDE option. Tapping this removes the application from the Purchased view.
Doing so hides, but does not remove, the application from past purchases which are all automatically recorded by iCloud, so the app can always be re-downloaded for free: searching for it in the App Store will still show an iCloud redownload button.
4/ iOS 8 lets you hide (-ish) photos — Users now have can greater control over their privacy with Apple iOS 8. Pictures can be hidden from the Years, Collections, and Moments views in the Photos app by simply long-pressing a picture. This pops up a menu with options to ‘Copy’ or ‘Hide’ the image.
Once ‘Hide’ is tapped, iOS 8 presents a warning informing users that “This photo will be hidden from Moments, Collections and Years but still visible in Albums.” Users can then choose to verify they wish to hide the picture, or cancel.
5/ Load desktop versions of sites when browsing — Load a website in Safari on your iDevice, then tap the address bar to bring up the Favorite menu. Now swipe downward on the icons to reveal the new “Request Desktop Site” button. (On mine, I have to tap in the URL bar and then flick downwards to get this item – Apple Insider has more detail.)
