Is your feature request related to a problem? Please describe.

• No, just an idea.

Describe the solution you'd like:

• Add ability to use {player} in "cmd-start" language path to see which player shortened countdown.

Describe alternatives you've considered:

• No alternatives.

Additional context:

• Consider adding {time} to show the shortened countdown.
• Also consider changing "/bw start debug" to "/bw forceStart" because forceStart works like start.
• (^ Additionally make /start command like /leave)
