Changing MultiView Settings from MultiReview
Based on what you see in reviewing a log file in MultiReview, you might want to change some of the settings that
you will use for a subsequent run in MultiView. For example, you might notice a specific event in the log file that
you want to take a closer look at with another MultiView run. MultiReview makes this easy to do by allowing you
to open a MultiView settings file, make changes, and save the file without leaving MultiReview. In MultiReview,
you can change MultiView settings for Go/No-Go events, for filters, for time-domain formats, for FFT sample sizes,
and for the user-specified information.
