The Mozilla Calendar component has been redesigned to improve its user experience and functionality. The new design offers better organization and integration with other calendar applications.
Currently, the name 'Sunbird' is a project name and not official, but it might change in the future. The developers have designed this application with an intended user in mind - someone who uses Mozilla Firefox and Mozilla Thunderbird and is looking for a reliable calendar application based on Mozilla.
The developers have focused solely on creating a standalone calendar application; hence they believe that they can make significant progress in improving the overall footprint and performance of the application by removing unnecessary components and chrome.
Though Sunbird is still in its experimental stage, it is generally stable, and the developers encourage testing to help with constructive feedback. If you are looking for a lightweight, user-friendly calendar application, you should give Sunbird a try!
