I have a few Bookmark folders I regularly open as a group, and they have multiple (sometimes 5 or 6) login pages on them, which results in 5 or 6 separate prompts for the Master Password.
There is one thing you could do fairly simply that would help (see [1] below), but what would be really kewl is if you could find some way to implement [2]...
temporary
[1] Display the Account Name (or 'Using URL' if using the 'Defaults') on the Master Password Confirmation pop-up.
permanent
[2] When a Master Password Confirmation pop-up window is already open, 'capture' subsequent prompts 'into' the same window, displaying them in a list by either Account Name or 'Using URL (for those that are using the 'Defaults'), and then when the User enters their Master Password, PM magically uses it for all of the prompts in seccession.
Result: Now, if I open a group of tabs that has 5 login pages on it, I get only one Master Password Prompt, and only have to enter my MPW once for all 5 sites!
What do you think?
