Analysis

Overview

The PRO_LIB change manager tracks undo/redo changes made to properties.

The goal of this task is to provide an end user interface to the change manager. Add a user interface via the Edit menu for Undo and Redo. I don't think we should expose skipping, as that would be confusing to the user.

Task requirements

• Add menu items to the edit menu that tracks the state of the change manager
  • Undo works down the stack
  • Redo works up the stack
• Add key commands (control-z, control-shift-z for redo) to the menu items
• Disable the menu items if you are at the proper end of the stack
