exclude drafts from conversations

I would love to be able to select which folders are shown in conversations. Trash isn’t included, obviously, but I would also like to exclude Drafts.

I though maybe unchecking show in communications and attachment history would do it, but no luck.

I am also having this issue and thought that all of my emails were sent off in the draft state at each time an edit was made.

I guess it is just you and me MT. In almost a year no-one has shown any interest in this proposal. ;-(
