Hate the brand-new schedule in Vista? Not a fan of the Outlook calendar or do not like the suggestion of constantly being linked to the internet to make use of Google’s Calendar? Love Open Source and also all things Mozilla? After that Sunbird is for you. Sunbird is a stand-alone schedule application. If you want Sunbird to integrate with Thunderbird then you would want to install the Lightning extension.
Out of package Sunbird has a spick-and-span interface. For you Firefox followers navigation will certainly be rather user-friendly.
The Options as well as settings are very simple like with Firefox.
As with Firefox there are lots of expansions to add functionality to your calendar. For a stand an only calendar Sunbird is a whole lot more encouraging than Windows Calendar included in Vista.
