Rated 5 out of 5 stars

An excellent add-on, which I'm surprised no-one thought of sooner. It is great to be able to see which weekends are free until the end of the year. Ok the re-draw is a tad slow but only superman in a hurry would be put out by the very,very brief delay. I Hope it will work with Lightning 1.0 beta2 which will be available soon to coincide with Thunderbird 3.1.

This review is for a previous version of the add-on (0.3.0b3).
