I use it all the time too, but I can't stand how I always have to retype my iTunes password to reactivate it. I don't know mine from heart, so it's like an every other day deal where I have to type in my passcode, go into 1Password, type in my 1Password password because I can't use Touch ID with it until I activate it, press my Apple ID in favorites, press on the hidden password, copy it, and then lock my phone, try Touch ID again, and then enter my password.
Probably wouldn't be allowed in the App Store, but I'd really like a widget where I could hide some frequently used passwords with a small passcode. I could easily paste some in Heapo, but I don't know, it bothers me that it's in cleartext in an app that syncs.
