BorderExpander automatically expands or contracts your world border daily at a configurable time.

All settings are in config.yml:

• time.timezone - Timezone for expansion time (e.g., "America/Los_Angeles")
• time.hour - Hour when border changes (0-23)
• time.minute - Minute when border changes (0-59)
• border.initial-size - Starting border size in blocks
• border.expansion-amount - Amount to change border by each day (positive = increase, negative = decrease)
• border.min-size - Minimum border size
• border.max-size - Maximum border size (-1 for unlimited)
• boss-bar.enabled - Enable/disable countdown display
• boss-bar.title - Display format (use {time} for countdown, {size} for border size)
• boss-bar.color-far - Color when >6 hours remaining (GREEN/YELLOW/RED/etc)
• boss-bar.color-medium - Color when 1-6 hours remaining
• boss-bar.color-near - Color when <1 hour remaining
• messages.expansion-message - Message when border increases (use {size} placeholder)
• messages.decrease-message - Message when border decreases (use {size} placeholder)

• /be expand or /be force - Manually trigger border expansion
• /be info - Show current border size and time until next expansion
• /be set <size> - Set border to specific size
• /be reload - Reload configuration and data
• /be help - Show command help
