Klaus, a hearty congratulations to you!! I had used the old and long unsupported Expression Search addon years ago. Then just looked for updates and found this one...supported. You, Klaus, are MY HERO! This addon has been a game changer for me. It's makes it amazingly easy to filter and find exactly what I know is in a mail Folder. THANK YOU, THANK YOU for bringing productivity back to my Thunderbird!

PS: Mozilla: Why on earth is this addon not standard?!
