= Analysis =

== Overview ==
There are some problems with the significance of model changes and the meta changes for them. 

== Task requirements ==
 The model changes should be undone and redone in a group:  [[BR]]
 
 * All sequential changes of the same type made for a short period of time: [[BR]]
  * Writing text [[BR]]
  * Changing color in the color picker. [[BR]]

 * Changes made over the same model of the same bound control without closing it. [[BR]] 

== Task result ==
The result of this task will be source code.

== Implementation idea ==
Change the way model changes are grouped for undo-redo operations. It is good for the significant change that groups all insignificant to be registered first instead of last in the group.

== How to demo ==
Open the appearance hud. Change the color of the border gradually and then undo it in one undo operation.
Insert text frame. Write some code, wait for a little while and then write some code again. The undo-redo of the writing text should be done it two steps.
