First of all, thanks very much for the 1Password app. I'm in love with it.
Since Google Drive supports 2-factor authentication, it is harder for an adversary to get access to my G-drive data than to my Dropbox data. For this reason, I'd be more comfortable to put my Agile Keychian in G-drive instead of in Dropbox.
Is G-drive sync on radar for the 1Password team?
