I'm a tagging enthusiast and I have a lot of data in 1Password. Frequently I forget which is the name of a site or web service I want to visit, but I remember the associated tags that I saved with this account.
Currently I can't just fire up the Go & Fill menu in Chrome and search for e.g. "tv" because I'm unable to remember that I should type in "next-episode.net"… so I have to fire up 1Password and find what I've been looking for there.
The browser extensions would really benefit from this feature and I hope this is already in your coding oven. Is it? (Please say yes).
All the best, Patrick
