Creating a new preset is simple: you just need to enter all the parameters for that preset.
When you add a new preset, the presets window will take the actual Comparator Fast parameters in order to save time.
When a new preset is being created, you must specify a name for it (any name or description to help you remember what's that preset about).
You may change any option as needed when adding a new preset, or later using the Edit Preset command at the main menu.
You may click on "folder search" buttons () if you want to browse for a folder.
Click the Add button when finish, then Close button to exit.
