Rated 5 out of 5 stars
Another good example for an Addon that adds just the right amount of "missing feature" to my beloved Thunderbird.
It works also very well in search results and removes one more unnecessary step from an operation that I do frequently. Thanks for adding the account column as well. I can see that this is going to be even more useful in the future as you have added custom fields so it looks it should be easy enough to add more useful information here in the future.
keep up the awesome work!
