Show unlock dialog on all monitors

Hey!

It would be great if it was possible to (optionally?) show the unlock dialog on all monitors in parallel. Reasons:

• The machine might have been brought to a different location and the monitor setup chosen while locked might not have handled the relevant monitor correctly (the one chosen to show the dialog)
• The logic to decide on which monitor to show the dialog can be unexpected (not the primary one?)
• Some monitors might take a long time to wake up from sleep, while others are quick. I'd love to start typing my password into a dialog visible on a fast monitor while the slow ones are still busy.

This is not super important but would be a good addition, imo 😄

Thanks!
