In Safari advanced settings, you can set a custom style sheet.
Just create a css file on your mac, where you want and put:
#op-menu {
margin-top: -200px !important;
}
Or
#op-menu {
margin-left: 300px !important;
}
Or whatever css you'd want, but this works, it will move the window up the fields instead of down, not so pretty, but working!
