I know there's already a link in PA.com for a calendar extension, but Mozilla is no longer working with it, instead they are working on Sunbird (a whole calendar app that John already has made portable) and Lightning (which is a TB or FF extension, similar to Calendar)
So here's my request. With calendar you could add a parameter to open the calendar without opening TB (see here). Is there a way to do this with the new Lightning extension? I'm guessing the only thing we (I) will need is the launcher to open the calendar. Thanks.
