Would like to see these enhancements made to Thunderbird: # Add recipient email address to view. This could be added next to the sender email address, separated by something like a pipe character "|" and identified by "From: ", "F: ", "Sender: ", or "S: " in front of the sender address and "To: ", "T: ", "Recipient: ", or "R: " in front of the recipient address # Add search filter terms to search capability. Some example filter terms would be 1) "mailed-to:" or "recipient" to search for emails sent to a specific email address or domain (using wildcard), 2) "mailed-from" or "sender" to search for emails sent from a specific email address or domain (using wildcard).
