I've been waiting for this for years... literally!
Thank you... but it is missing some important features like List management (create, delete, rename), move tasks to specific List, sort tasks, ident/unident.
Hopefully this useful addon will evolve or even better, its' features will be included into the latest versions of Lightning.
Sorting tasks and indenting them is already possible; use the drop-down menu next to the sync button.
Managing task lists and moving tasks between them will be added at some point in the future. This add-on aims to offer the same functionality as Google's web interface, so anything functionality present there can be expected to eventually appear in the add-on.
