Describe the feature

Simple feature (for those who know the codebase better than I). This would make suggestions hidden while typing and wait for a user pause of chosen time.

Main goals The primary goal is to not show information when it isn't needed (or wanted).

• Most of the information displayed is never read (only on screen briefly between keystrokes), and what is read is usually done so during a pause.
• Subjectively, things that blink very quickly -- like with every keystroke -- are not enjoyable.
  • Flow state is easier when there's less interruptions.
  • Having to ignore interruptions contributes to mental fatigue
  • Blinking things do not create a relaxed environment, something which can be very nice when low on energy or deep in thought.

How it would work:

• user sets the show_completions_on_input to something representing a millisecond delay (number, string, w/e)
• user begins typing, no completions are shown
• user continues typing, no completions are shown
• user stops typing for the millisecond delay, completions are shown
• user continues typing, completions disappear until the next pause
• user finishes what they were typing (whitespace, semi-colon, etc) or selects a completion, the completion overlay goes away

The I find most debatable about this suggestion: UX question: Should the completions disappear when someone starts typing again? Does this require more than one setting to give proper control? If so, is it worth adding an extra setting?

IMO, I don't want to see anything but what I'm typing while I'm typing. I would likely set my pause in the range of 300-600ms.

If applicable, add mockups / screenshots to help present your vision of the feature

This was originally a question. In it is a video of me typing and my screen going -- humbly -- totally wild:
