== Overview ==
The goal of this task is to develop a concept of describing Changes with useful end-user information.

This includes:
 * Reviewing current implementation for information and descriptions associated with Changes
 * Giving ideas for new types of Change descriptions which will be useful for the end-user
 * Devising a mechanism to implement the ideas above internally

== Task requirements ==
 * Information about changes should be classified by types and implemented:
  * Description
   * When the user is undoing/redoing a change, this results in a top-level change which should have meaningful description
   * Internal side effect changes could also have useful descriptions
  * Whether the change is a main or a side effect
  * Unique sequence id of the change
   * When Changes occur, they are sorted in order of appearance so each Change should have a unique id
   * The smaller the id of a Change, the earlier in time it has occurred
  * When the end-user views a top-level change, besides description there should be also a timestamp of the Change, e.g. when it has occurred
 * Develop a UI tool which shows the tree of Changes for debugging purposes
 * Develop a proper way to visualize what kind of effects undoing/redoing a Change would have
 * Create new unit tests

== Task result ==
 * Description of the information a Change provides in the wiki page
 * New code to implement the desired functionality
 * Description of the UI tool in the wiki

== Implementation idea ==
 * Use the Inspector for a base of the UI tool

== How to demo ==
 * Undo/redo some actions in Sophie 2 and show the descriptions
 * Show the UI tool
 * Run the unit tests
