title: Is it possible to use a custom Class in Properties.Settings.setting
body: <p>I know that it is possible to use settings to store some default values or user settings of program.</p>
  
  <p>But I need to make a setting that can hold a class that I wrote myself. Is this possible? I can't see the classes I made myself, in Type or Browse... column of Settings.</p>
  
  <p>Thanks.</p>
