I used to be able to run a short preview segment for each of various models and then switch between them for an A/B/C comparison, to decide which model I preferred for a video. These previews are no longer saved as I switch between them in v 6.1.3, making my choice more difficult.
In version 6 with the introduction of tabs this changed the preview workflow. Now you will need to open a new tab and set that for the next model you want to preview. Then the tabs can be moved from the left or right side as needed to review them.
