Tags
A tag is a keyword that is used to categorize an entry. To view the entries with a particular tag, click a tag name or enter a tag in the box.
The tag cloud indicates the frequency of tag use. Popular tags appear darkest. The slider control adjusts how many tags are displayed in the tag cloud.

I will throw this it out, it may not be it, but Notes 8 has the new feature where it will show the entire thread of messages. You see this as a twisty next to the subject, and when you click on it it expands and shows you the entire thread of messages on that subject, and does grey out the inbox.
@1 - Yes, it looks similar to that, but there are no conversation threads open, and I can still click on any email and open it.
It also may only happen with the preview pane open, but I have not
confirmed that.
