MEET YOUR FAVORITES: Having all those images at hand might make you nervous about ever finding anything again. Apple has anticipated your concern, though, by adding both a smart search feature and a Favorites section. The search field will initially prompt you with a collection of nearby photos, images taken at the same time last year (for nostalgia factor), and all-time favorites; but you can also search by date or time, location, or album name.
Under every picture in your library is a small heart outline; tap the heart to fill it and add the image to your Favorites album. You'll be able to access that album on any iOS 8 device (or, in 2015, on your Mac), and any edits you make to those images that automatically sync.
HIDDEN IMAGES: Sometimes, we take photos we don't necessarily want to keep in full view. iOS 8 allows you to hide those unwanted images from the Moments, Collections, and Years sections of the Photos app, though they'll still appear in albums. To hide an image, just tap and hold on its thumbnail, then tap Hide; it then vanishes, relocating to the Hidden smart album. To recover the photo, just visit the Hidden album and tap and hold the thumbnail to unhide.
UNDELETE: Unlike past versions of iOS, when you delete an image in iOS 8, it's not immediately removed from your device. Instead, it retreats to the new Recently Deleted album for 30 days, at which point it's expunged from your device.
This is primarily to prevent you from accidentally deleting that perfect picture when you're weeding out duplicates and blurry images, but it's also a nice way to temporarily remove images you're not sure you want to keep. You can dump this entire folder quickly by going to the Recently Deleted album, tapping Select, then tapping the Delete All button.

In iOS 7, the Photos app offered a few basic editing features and filters, but for anything fancy, you needed to download Apple's iPhoto app. In iOS 8, iPhoto has been retired, and bits and pieces have made their way into the Photos app, offering you all sorts of advanced editing features.
Download an image to your device, and you'll be able to use a bevy of iPhoto-inspired features to crop, straighten, remove red eye, adjust lighting and contrast, and more.
