Nice, but needs improovement Rated 4 out of 5 stars
Lightning is a really nice add-on, but it still lacks some functionality:
1 - Option to hide the side panel, that would reduce a lot the screen clutter
2 - Multi week view, there is an extension to do that, but it doesn't work on tb 2.0.0.*
3 - Better alarm system, with more options
4 - Invite system, similar to the one found in Google calendar. (BTW there is a great extension to use Google calendar in Lighting)
The development has been really good so far, so thanks to those that have worked on this and congratulations!
KAH, Thanks for the 86-64 link! That and i686 links should be on the lighting page, no hidden in a repository ;)
