* The generated Python code will setup a window without menus and palettes. It will only be a plain canvas. Turtles will be visible with their (default or custom) sprites because this is the only way to make sprites move in TA. | * The generated Python code will setup a window without menus and palettes.

* Code in named stacks will be put into functions with the same name. Blocks appended to the 'start' block will be put into a function called <code>start()</code>. Unnamed stacks will also be put into extra functions with auto-generated names (e.g., <code>unnamed_stack_1()</code>). | * Code in named stacks will be put into functions with the same name.

* Run only the block stack that has a 'start' block at the top. If there is no 'start' block, notify the user, but don't execute unnamed stacks. (TA itself should show the same behavior.) | |||
