This article introduces the most interesting new features, improvements, and changes visible to users which are available in Thunderbird 128 Nebula.

Cards View improvements

• To be consistent with Table View, Cards View displays a green dot to indicate unread emails (prior versions did not display anything to indicate that the email was unread in Cards View).

  

• The starburst (for new messages since the last time this folder was opened) indicator for both Cards View and Table View is now a yellow diamond (previously, it was a circle for Cards View).

  

Accent Color

Thunderbird now offers improved theme compatibility, which is especially beneficial for our Linux users on Ubuntu and Mint.

For example, in Ubuntu if you change Ubuntu Settings > Appearance > Color to purple, you will see selected emails outlined in purple as seen in the following screenshot of Cards View:

Mailing List improvements

You can now unsubscribe to mailing lists, open list archives (on the web) etc. for mailing lists that support standard headers such as List-Unsubscribe and List-Archive, etc.
