I really like the 1Password UI in Chrome and Safari (the Safari one I know is brand new, which looks more or less the same to Chrome, which is good!), but the UI for Firefox seems unchanged since, well, ever since. Is it possible, feasible, in your plans, to make that UI the same as Safari and Chrome's? It would be great if it were unified like that, and it'd just look so much better than that list that pops up, or the rather bland toolbar (which takes up precious screen real estate).
Well, that's my 2cents anyway. You guys are doing a great job, I just wish that the Firefox UI looked as nice as the others (since it is my browser of choice).
