Can be good, and probably usually is - but can be bad / frustrating too. Rated 4 out of 5 stars

Most of the time, a wonderful tool.

I DON'T CARE if it doesn't find EVERYTHING, I DO CARE that it DOES NO HARM! And as far as I have been able to tell - that's true. So, WONDERFUL! and THANK YOU!

Sadly, I see no way to get help. I wish the developer had an add on developer page where people could help each other.

Currently, it gets mysteriously stopped for me on a particular mailbox - gets up to ~330 / ~50k, then stops. mysteriously. No obvious way to see how / what is going on. Therefore, two suggestions:
(a) Have it pop up the dialog, not just carry on in the background. Log what its doing, perhaps with more/less verbosity. If I could see what's stopping it, I could go fix it.
(b) Instead of debug out (ONE MESSAGE AT A TIME, FOR PETE'S SAKE!), have debug out go to error console. Without needing to hit OK for each message. [Even then, if the message it stops on is shown, the format of the message display doesn't make it too clear as to which message to go to to fix whatever's wrong. I expect it's a botched e-mail message (to TB), but I can't fix what I don't know / can't find.)

The initial dialog would be a useful pop up to select which subfolders not / to check. e.g. In this case, if I knew what subfolder was causing problems, I could exclude it.

I really appreciate the new info present in the options dialogue, e.g. Usage, Help, About. Just wish it gave more info / pointed to a more info web page. e.g. Developer addon discussion page. Even if the developer stayed out of it / let the users merely mill about.

Despite any of the above, thank you so much for this addon.
