Mozilla Lightning for Linux v0.8
I really was not that impressed. The linux version of thunderbird isn't great to start off with and already has it's own internal calendar and planner (of sorts).
<br/>
<br/>I wasn't impressed by this addon. It isn't enough to make me change from Evolution to TB in the near future.
<br/>
<br/>Looks like mozilla team still have some work to do. TB has faults and problems with font renderings and locales which really should be solved as a priority rather than dressing up a faulty application with more bling.
<br/>
<br/>C'mon mozilla.. get TB sorted properly first and then do the dressing up later. Until then there are lots of finished and slick linux mail client alternatives.
