Rated 4 out of 5 stars

It's everything I wanted as I work in a Google Apps environment. The only thing is that the red "this is the time" line isn't accurate. Not sure if that's a bug or my settings. Refreshing calendars doesn't help. Other than that I would give it 5 stars. Looking forward to v.4!

Thanks for the reply. I've changed the calendar.view.timeIndicatorInterval to 5 minutes, hopefully that will help without hogging too many resources.

This review is for a previous version of the add-on (0.4). 

Settings. Not exactly yours, but rather Lightning (not even Lightbird) default settings. I honestly don't know if that's how it always been or it has been changed just recently, but please see this: https://github.com/Exalm/lightbird/issues/15
If it's not the same, feel free to reopen that bug.
