Every application needs documentation. For this we use the annotation feature to document our microflows. Now I wanted to find the microflows where we forgot this. I played with find advanced feature but could not find a way to do this. Should I file a feature request or am I overlooking something?
Don't think this is possible no.
What you could do (hindsight is 20:20!) is add a TODO annotation in every new microflow. That way you can easily check them simply by searching for 'TODO'.
I suggest filing a feature request either way.
Edit: Also, you can use the Documentation tab to add documentation to any document.
