VStar Plug-in Library

One of the features of VStar is that it is set up so that you, the user, can think up new and interesting new ways to use the basic program. You can do this by creating your own plug-in or by using ones that others have created to extend the power of VStar. If you are interested in creating your own, please read the documentation on how to do this. If you would like to see some plug-ins that others have created, you have come to the right place.
