it would be great if Message list themes get the ability to show user avatar. Could make KMail much more visually appealing and helpful, considering the new gravatar support. Reproducible: Always
message list theme ? What is it ? in viewer ? or list of mail ?
I meant list of mail. And that tool you can use to create new themes for it with drag&dropping widgets/columns.
If I understand this wish correctly, you'd like to see a small avatar in each message line of the message viewer that is associated with the sender of that message, and a way to place this avatar in the message list theme editor in "Settings -> Configure KMail... -> Appearance -> Message list -> Default theme -> Configure...", right? In this case: still valid for 5.4.1.
As an example just have a look on eM Client. There the message list has a separate column showing the gravatar of the sender.
Created attachment 158129 [details] Added example screenshot. In my opinion, the avatar makes it easier to find mails in the list at first glance.
