Rated 3 out of 5 stars

Works fine in 78.0.1 here, but only for individual accounts. Unfortunately, in "unified view", it doesn't work at all.

This review is for a previous version of the add-on (1.0). 

Hi D,
Sorry but I am not sure what you mean by unified view. The only unified view i can see in TB is for unified folders and the addon still works for this view. You may have been having an issue with a bug that has now been resolved related to having over 100 unread messages in a folder.
Thank you.
