Hello, I want to build an extension, that will have a custom table shown, instead of the default one with Subject, Correspondents, Date, I would like to have for example, Name, User, Status. I've managed to add custom column, but i cannot remove the default ones. So my question is, is that even possible to do? Could i somehow create my own html or xul, that will be rendered in the threadPane view instead of the default one? Is there some kind of a function that i can access when im creating an extension. Hope my question makes sense. Thank you.
