Rated 4 out of 5 stars

Great add-on. I can't go back to the original view now. Two suggestions:
- The one thing I miss from the old view is the "detach" option to save and delete attachments in one step.
- With this add-on, reading and deleting emails is slooooow. Hopefully it can be made swifter in future releases.

This review is for a previous version of the add-on (2.5.2). 

First item : use right-click to access the detach operation
Second item : unfortunately the underlying subsystem in Thunderbird that this addon relies on has some performance limitations...
