http://source.squeak.org/trunk/Tools-ct.1031.mcz

==================== Summary ====================

Name: Tools-ct.1031
Author: ct
Time: 10 March 2021, 6:26:41.374559 pm
UUID: 90289614-021a-254a-b67f-5612c973d257
Ancestors: Tools-mt.1030

Fixes styling in change sorters if no real method is selected. No need to invoke Shout on messages such as "method was removed".

Using an instance variable for this to avoid duplication of the contents logic.

  myChangeSet

  	-the dual changesorter that contains this one. Used for dealing with the other half.
  priorChangeSetList
