In this same conversation with a colleague, she told me she was confused by the green and blue notification bubbles. She could not figure out what the colors represent, and she was especially confused because she had alot of both of them. In this case, she has moderator privileges but does not log in often - mostly she participates by email.
Correct me if I’m wrong, but besides the red flag-related bubbles, I think the green notification bubble only shows how many new personal messages you have while the blue notification bubbles are for everything else.
I know there are probably very good reasons for having a separate green bubble for personal messages, but in my community I don’t think there is any need and they are confusing. Perhaps an admin setting could be provided to simplify the UX and just display a single blue bubble indicating the number of new notifications?
