Try this
- Label versions by purpose, such as private thoughts and possible message, instead of relying only on numbered filenames.
- Before copying text into a conversation, read the whole selected version and check attachments or quoted material.
A worked example
“Private thoughts stays in my notebook. Possible message contains only the request I am considering sharing.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
A later version is not automatically the one you want to send. Keep the send decision separate from which file was edited most recently.
