Inventory Security: Implementation of a custom InventoryHolder to ensure the plugin only saves data from its own chests, eliminating conflicts with third-party menus.
Hybrid Storage System: Native and switchable support between SQLite (local) and MySQL (remote) via a dedicated DatabaseConnector.
Intelligent Backup Management: Automatic creation of safety copies (.db) on startup, featuring a rotation system that keeps only the most recent files (configurable).
Migration Engine: Automatic mass conversion of legacy .yml files to the SQL database, including safety renaming to .bak for data preservation.
Command Hardening: Dynamic TabCompleter and rigorous validation (try-catch) to prevent any console exceptions, such as NullPointerException or NumberFormatException.
Registration Priority: Injection logic via CommandMap to ensure the /pv command belongs to VirtualChest, even if other plugins attempt to register it.
Internationalization (i18n): Complete centralization of all messages and logs (including console output) into YAML files for four supported languages.
Performance Optimization: Database-heavy tasks (saving/loading) are executed via AsyncScheduler to prevent any impact on the server's TPS.
