- Added configuration to automatically open generated files in the editor with a customizable limit.
- Enforced strict project-scope file selection for i18n and XSD settings.
- Switched to relative path storage for i18n/XSD configuration to enhance project portability.

- Fixed compilation errors and optimized imports in configuration classes.
- Bumped plugin version to 3.2.4.
