How do I get rid of the line before sender name

Hi Mitchell The app doesn't provide an ability to remove the line. Its colour identifies the account containing the email, and is only displayed within Unified Inbox. Feel free to raise the suggestion on Mozilla connect for its removal or any ideas you have to improved it. The community can then vote for them. https://connect.mozilla.org/t5/ideas/idb-p/ideas/label-name/thunderbird%20android
