Option to add space after recording.

I like to dictate sentence by sentence sometimes and always then have to manually hit the space key before I can dictate again.

I would like the option to change that behavior in the settings.

Thanks for looking into this.

No files, tests, or entry points are named; begin by locating the recording flow and the settings screen. Done means users can enable an option that inserts a space after each recording, while preserving the existing behavior when the option is disabled.
