How many levels of undo does Dr. Beam support?
Dr. Beam currently has 10 levels of undo (and re-do). This can be a simple way to sequence a presentation of a series of steps in an analysis. First, do the steps ahead of time, and then undo back to the starting configuration. For the presentation, simply replay the steps using the re-do command. If there is significant demand for additional levels of undo, we can make special accomidations. This would, however, require additional run-time memory to operate Dr. Beam Pro.
