Stopwatch Plugin

• /stopwatch start — starts a new stopwatch at 00:00 in green. An existing stopwatch must be deleted first.
• /stopwatch pause — freezes it and changes it to orange.
• /stopwatch stop — freezes it and changes it to red.
• /stopwatch unpause — resumes a paused or stopped stopwatch in green.
• /stopwatch delete — removes the stopwatch and clears the action bar.
• /stopwatch settings — opens a GUI that enables or disables stopwatch sounds for that player.
• /stopwatch time add <seconds> — adds testing time; requires stopwatch.time.add (operators by default).
• /sw is an alias for /stopwatch. Displays refresh once per second and expand from MM:SS to HH:MM:SS, then DD:HH:MM:SS.

Sounds are enabled by default. Starting or resuming plays entity.arrow.hit_player; pausing, stopping, or deleting plays block.wooden_pressure_plate.click_off. The GUI preference persists in the player's saved data.

Trying to start a second stopwatch shows a bold red warning and always plays block.anvil.land, even when stopwatch sounds are disabled.
