An optional feature to make the lock screen more similar to Android/Windows etc. would be nice. To explain it in more detail: Currently, when any key is pressed, the password prompt is shown and is also registered for the password prompt. What I'm suggesting is that the first key press is *only* used to show the password prompt, and a second key is needed to be registered for the password prompt, as well as remove mouse movement from showing the password prompt.
This would be terrible! A major complaint that people have about those systems is that you *can't* start typing your password immediately. It is super annoying. Anyone who prefers this is suffering from Stockholm Syndrome. :)
