I've been a very happy 1Password user for many years (before it gained its vowels). The current series of Safari extensions has one issue that concerns me though, but should be fairly easy to address.
When I pop up the 1Password popover (usually with Cmd-\), I'm often asked to enter my master password. I can't tell in advance if I have to do this, and it seems I usually do, so my fingers are used to the flow of Cmd-\, <type master password>. Unfortunately if it's already unlocked, I still end up typing the first few characters of the master password (as the popover takes a moment to appear), which are then used as the filter and become visible.
This has happened enough times to worry me a bit. I'd like if those first keys I type instead make the system beep, or something other than become visible.
I've just poked around in the prefs and un-checked "disable automatic unlock", so hopefully I won't run into this again, but it's a default that I feel is inappropriate.
Thanks for all your great work!
