How exactly are the presets applied ?
A preset is a snapshot of settings, you can apply a preset by importing it’s settings into the MagicPrefs settings, the MagicPrefs settings are what you are seeing in the preference pane and are applied globally. However presets can be also used without importing the settings from them, by assigning a application for a preset that application ignores the global settings and uses the settings from the preset it is associated with.
