New version available. The links are in the first post. I haven't tested the 3537 version so I can't confirm if the gui works in that version. The plugin now has two modes. When you change the mode, text is displayed in the header of the window, telling the user to close and reopen the window. The mode only change once the window has close and reopened. I changed the coordinates system. It did not make sense to put the 0 in the lower left corner. It's now in the middle. Please report any bugs or strange behaviour you encounter with the plugin. If the plugin becomes good enough, I'll give the source code to Eugene so he can put it in the next driver release. Currently, the user has to manually close and reopen the window. In the future it will probably be automatic because of help from Eugene.
