Love seeing my old thread revived. I would still like swipe to Archive from the Sent folder for the benefit of other like-minded souls.
But in the meantime I've given up on that dream and worked out a new workflow that's even better. I went into Settings > Identities & Fetch > tap on an identity > Show advanced settings > Save a copy of messages I send from the identity in my Inbox folder
Copies of outgoing emails end up in the Inbox instead of the Sent folder. I can immediately swipe to archive from the Inbox after sending an email. I even went into the Folder Settings to hide the Sent folder entirely. Problem solved, quicker to perform this action, and one less folder in the tree
I love how different people use email in different ways and Fastmail allows us to do whatever we want, or find interesting ways to get around the limitations imposed
