Lightning Striken Rated 5 out of 5 stars

Without a doubt, Lightning is nearly as essential as Thunderbird itself in my day. The integration of Lightning and Thunderbird is an unbeatable combination. Thank you for maintaining and improving Lightning.

Lightning is Indispensable Rated 5 out of 5 stars

Lightning is the single most important addition to Thunderbird's productivity. It has become indispensable in my daily work, and organizational ability. Despite the occasional bump in the road, the development team continues to improve, fix, and add features. I look forward to the future of Lightning, and thank the developers for sharing it with the community.
