Taking screenshots of steps and tips is possible as of version 21.0. Clicking on the monitor icon in the editor will show you a screenshot of that particular step.
Or by selecting the arrow in the screenshot, you can see the full slideshow of the journey selected. This is useful in case the journey needs to be amended, and you are not sure for example what particular element was selected for that step.
It might happen that journeys and tips created with an older version of the editor are not visible, you can add them by taking the screenshot.
Click on the camera and the screenshot will be taken. The screenshot is automatically saved and does not need to be re-done.
