Allow deleting individual message in thread, not only entire thread
Feature summary
Many times I have deleted entire email threads when I intended to delete only one message. The 'delete' menu item is ambiguous when it is viewed in the contextual menu for a single message. I expect it delete only one message but it deletes the thread.
How would you like it to work?
Make the contextual menu for a message delete only the single message, not the thread, or warn the user what action will be taken to avoid ambiguity.
