With official, system-wide extensions on the way, the potential
for Mac and especially iOS apps to work together expands
immeasurably. Actually, it explodes in an invigorating display of
colors, delightful sounds, and hope. Apps like 1Password can fill
information directly into Safari forms and all the other apps that
add support. We can archive webpages in Evernote and Stache.
Afterlight — really, any photo app — can edit photos right in
the Camera Roll. Even better, I’m just barely scratching the
surface of this potential.
Part of the genius of these extensions is the way they’re bundled with the apps. So if you have the app installed, you’ll see its extension in other apps automatically. And if you don’t, you won’t. And if you want to get rid of an app, you don’t have to do anything extra to remove its extensions — they get removed when the app gets removed.
