Add tool-tip feature to correspondents column to aid spotting spam emails in Thunderbird.

[RobertS2024]

#Thunderbird. In the main message list, if I mouse over and stop at an entry in the subject column I get the full text of the subject presented as a tool-tip. This is helpful when the subject column is short and shows only the beginning of the subject.  It would be very helpful to have similar expanded info for the correspondents column displayed in a tool-tip when I mouse over it.  The expanded info should include the full email address of the sender, not just the "nice" name which is too easy to fake.  This would very much aid in the recognition of spam (or unwanted) message and allow them to be disposed of without needing to open more of the message.

The default display of the contacts was changed in a recent update to Thunderbird.  I know because I had to turn off the display of email addresses in that column because no one asked me if I actually wanted to change my default view.
