An async microflow call (microflow in Queue) changes the fundamental behavior of the calling microflow. This is especially true when the queued microflow handles some data processing that can allow for users to avoid a “please wait” state. There are also different considerations to take in regard to object commit states.
It would be great if the microflow action of calling a microflow action in queue had a visual indicator. My suggestion is a “Q” in the bottom left corner. Another suggestion could be a clock overlaid on the corner.
