MEXTool openand press Ctrl+D (or Cmd+D on Mac) to run the code and open the Morphplorer.
- OverView: The window that appears when you open the tool. It gives you an overview in which categories you could search for methods related to the Morphic framework
- ExplorationView: The window that appears after clicking on a category in OverView. Here you can select multiple methods from the tree (top left), see the morph before those methods were applied on it (bottom, left), the morph after those methods were applied on it (top right) and a codeholder to see how you can apply these changes with Smalltalk code and play around by changing the code and running it via the "Run code"-button or Ctrl+S (or Cmd+S).
In our wiki you can find the project's coding standards and the current class diagram, showing the architecture. For further information, please refer to the class comments in your image after installing the package.
