Hi
Given that opera widgets cannot interface with Opera, my request would be to move the "Input URL" dialog from the pop-out "Edit Profiles" window, to the main window. This would make it easier to use the "Default" profile because you would be able to past in the URL you're logging into.
A second request would be to have a slight delay after changing the contents of a field before the password is re-calculated. (See the desktop version). This is because the widget seems quite sluggish when typing into text boxes and the password being recalculated with each key stroke can't be helping. Like the desktop version, you could blank the "Calculated Password" box when a field is changed and start a timer. If more keys are pressed, the timer is restarted. When the timer ends (2 seconds maybe) the password is recalculated and displayed.
I did add a comment over at widgets.opera.com but I'm not sure if Caspian is monitoring this, or even continuing development of the widget.
Thanks
Andy
P.S. Full marks on the PasswordMaker system in general, just started using it after hearing somebody mention it on Security Now! podcast with Leo Laporte / Steve Gibson. They were discussing using "algorithms" in your head to come up with passwords for different sites, but it's a h of a lot easier to use a proper hashing algorithm, thanks guys!
