When an article is selected in the headers window, the associated threaded articles become automatically expanded. This makes it necessary to press the delete key several times to delete each of the articles within the thread, or alternatively, unexpand the article threads by hand prior to deletion. It would be useful to have the option to not automatically expand threads upon selection. I propose a new option as follows:

Menu: Edit, Edit Preferences, Tab: Behaviour, Section: Articles, Expand thread upon selection.

If the box is not ticked, then do not expand threads upon selection.
