The following are limitations in implementing new queueable objects:
A complete web page must be written to create and edit the new queueable object, as well as a page for selecting the object.
Any objects created this way will work in the Dovetail Agent environment, but the objects will not show up in the Classic Clarify Client console. The objects won't break the Clarify system - but specific classic-client forms will have to be written to show them.
You should consider data restriction ramifications of your new object (for data restriction users only).
