Top extensions in iOS 8 (hoped for)

Here are the top three extensions I am hoping to see in iOS 8:
1. Evernote.  Option for Evernote to become the default notes app.  New modes for the Camera app – Evernote document scanner and business card scanner.
2. Mailbox.  Default email app.  Hopefully then sending a bunch of photos by email won’t be so tedious.
3. Pocket. Option to add websites to Pocket straight from Safari.

Anyone have a different set of top extensions in mind?
