When I hit the app store to update my iPad today, I noticed an Evernote app update stating that we can now add "a colorful sketch" to our notes.
Given the fact that Android users have been able to do this for awhile, I'm surprised there wasn't more fuss made about this release. It's awesome news for iOS users.
Regardless, go update your Evernote app on the App Store! The drawing functionality is enough of a reason, but they've also added multitasking for iPads on iOS 9.
UPDATE: There's now an official blog post
