A new feature introduced in fastProject 4.7.3 and above is a simplified window function at the end of the Update to review the changes to each of the targets as a result of the Update. Selecting "Pull-in" will bring up the last baseline and show the critical path to the selected target.
The same "Review Targets" function can be selected at any time using the Inspector dropdown menu (above). This is a fast way to scroll through targets, get their status and then set-up for a Pull-in analysis. Notice in the top left corner that "5 day slip" on the selected target is visible. This is live and will change as the schedule pulls-in and pushes-out.
