Currently, it is only possible to delete an SMS message thread by clicking the Delete link in the thread list.
Therefore, deleting a thread after reading it requires closing the thread window, re-locating the thread in the list and clicking Delete.
It would be nice to be able to click a "Delete Entire Thread"/"Delete All Messages" link within the thread window itself.
