I am totally beside myself with the fact that someone had the aptitude to write such a great program in concept, but failed to allow the calendars to simply sync with Google upon a keystroke instead of relying on a constant online connection to send the data back and forth between Lightning & Google.
As many others have complained, I have found that this add-on brings Thunderbird's performance down to a completely unacceptable and almost useless level.
Yes, I have checked the "experimental" caching box to be able to view calendars offline... not good enough.
Yes, I have tried making the calendars "read only", but who the heck wants that?
Make this add-on a REAL and USEFUL tool on the next revision by letting the calendars reside locally on the PC and simply sync with Google upon command. Fast, simple, useful, always available.

This review is for a previous version of the add-on (0.5.1).

Maybe you want to join the Mozilla Calendar Project and help us improve performance? I can set you up with a few links to get started in development if you like
