In recent months the StackExchange dropdown has been added to the top bar in Stack Overflow et al. Upon opening, the drop down has three buttons at the top: hot questions, all sites, and inbox. Periodically, the inbox button will include a count.
Assumption #1: the count on the inbox button is an "unread messages" count. True?
Assumption #2: the inbox displays questions, answers and favorites. True?
Scrolling through the list of messages in the inbox, I would expect to see some visual indication reflecting the "unread messages" count. That is, if the unread count is 2, I would expect to see 2 messages highlighted in some one (shading, arrow, etc.). But I find nothing of the sort. How does one know which 2 are being referenced?
