How can I have two KM viewer windows on the same screen open at the same time both editing the same macro file, and the changes reflecting on the other viewer window live?
You can now – viva KM 9.0!
EDITED 2021/01/18 CST – Keyboard Maestro v9.0 added this capability.
Can't be done now, but it has been reported that it may be a feature of KM Ver 9.
It is working in KM9.
