We automatically take a snapshot of the draft diagram at the start of any editing session, when any editor switches to edit mode. You can also take a manual snapshot at any time by clicking on the camera icon in the upper-right corner of the screen when in edit mode.
Then you can add supporting notes.
To view the change logs, click on the "Changelog" tab on the right panel. You will see images for the last 10 records created. To open the Changelog Viewer to view all records in full-screen, click "OPEN CHANGELOG" at the top of any of the images.
The Changelog Viewer opens in a new tab in your browser. You can now view and filter all the manual and automatic records by date, sequence, and user.
