 **features**
 
-* allow matricies to function as radio buttons (1 on / all off)
 * save / load gui settings via external file
 * add additional gui positioning options that allow multiple panels to "snap" together
 * data-binding for all components? (need use cases)
 * dynamic gui creation via external api?
+* <del>allow matricies to function as radio buttons (1 on / all off)</del>
 * <del>add custom labels on gui footer</del>
 * <del>externalize all gui & component settings into templates</del>
