I have TB portable and I use POP3 to fetch my messages. Is there any extension, plugin or similar that allows me to see the new mail (for example, sender, subject, and size only) before fetching it and then DO AS I PLEASE message for message: delete it altogether from the server without fetching, fetch and delete from server, fetch and keep on server, etc. This saves downloading time and bandwith especially with foolish messages with big attachments. Now I have to fetch them to see them and then delete them from local folders and use the compact command. Foxmail has precisely this feature which is wonderful, but it has been banished by Google as of May 30th, 2022, and I have had to resort to TB. It is a fine email client, but I miss this precise feature which I have used for more than twenty years.
