2.1.1

Bug fixes:

• Improved macOS compatibility: Replaced deprecated path conversion function to ensure that notifications function correctly on macOS.

New features and improvements:

• Updated versioning: The add-on has been migrated from the legacy version format to comply with current standards.
• Duplicate notifications: Introduced duplicate notifications along with console warnings to simplify troubleshooting. This is particularly useful as Thunderbird notifications may be disabled in OS settings by default on some operating systems (e.g., macOS).
• Folder case sensitivity note: Added a note in the options to inform users about folder case sensitivity, enhancing user awareness and preventing potential issues.

UI adjustments:

• Icon size and element widths: Adjusted the icon size for Thunderbird notifications and fine-tuned the widths of the elements.
