In the Java User Interface (JUI), one can select multiple tasks within a workflow and then perform any of a limited subset of operations (Copy, Remove) on all of the selected tasks. The AWI should offer this capability too.
This idea originates in this discussion by @GJG:
When editing a workflow, is there a way to select multiple job objects for deletion?
This idea is included in the list of Java UI features that are missing from AWI v12.1.
