The text view in the Procedures window now demonstrates a certain amount of syntax highlighting - brackets, numbers, and operators are in various colours. This behaviour can be turned off in the preferences dialogue.
Procedures can be dragged from the Procedures window of one document and dropped into the Procedures window of another. Procedures within one procedures window can be reordered by dragging.
Right-clicking in the procedures table-view brings up a context-sensitive edit menu (cut, paste, etc).

A preferences window has been added. The turtle attributes (transparency, size, etc.) have been moved into this window and so are now global across documents.
