Tbird is close to perfect for me, so I regularly support it. One thing I do have occasional problems with concerns searching and using tags I hope I am wrong, but when I search for one or several emails I usually find them, but still have no idea of where they are located. The same applies to the very handy tags which I also gratefully use. I filter mails to appr 30 folders and archive them yearly, so actually finding an email can take some time. The path to the folder is not necessary - just the name of the folder would be enough to pinpoint it
