@cyberqueen, I must agree with Mad10. This is a work-around. A full and proper solution would enable me to choose, for any domain with multiple accounts, the default account to pre-populate, and then enable me to change that via your method should my default not be appropriate on a given day.
For domains that I visit several times per day, it would be faster to learn the password and just type it in, than use the cumbersome click-drag-click-drag-click-drag that is required now.
I am therefore adding my voice as a paid-up user to the choir of voices asking for this feature.
The product is very good, but improvements are what it's all about!
