Thanks to the 1Password team!
I wanted this feature since day one!
I noticed that my other vaults on 1Password for OS X were synced by Wi-Fi with 1Password for iOS!
Hi @Dean Lubaki,
You're welcome! We're loving this too.
It is not only syncing all of your vaults, it is now including your attachments as well. In addition, it is now sync'ing automatically in the background without requiring you to keep the Wi-Fi sync window opened.
It's also very fast. :D
