Preset parameters may be altered under the Adjust tab in the Variable Presets window. Once any parameter is changed, you’ll notice that the “Save Changes” button becomes active under the Edit header. The Preset will keep the original values stored until you save the new settings. Note also that the Edit header corresponds to the Setting under the Select Preset header. This means that even if you have the variables from one setting displayed under the Create or Adjust tabs, the Setting chosen at the top of the window is the one that Save or Delete will operate on. Take care that you don’t accidentally delete the wrong Preset! When you want to choose a Preset to alter, make sure to choose the setting then click “Apply” to set all of the parameters to the Setting values before changing others. This way, you won’t accidentally overwrite the parameters that you didn’t want to change with those from another Setting.
