Extend the Action Set action to include error handling
It would be awesome to be able to handle unexpected errors in a workflow for a subset of actions. Since the Action Set action is already a container for other actions, it would be helpful to extend it so I have more granular control on unexpected errors that might occur in a workflow. Similar to the Try... Catch concept in C#.
Unlike other actions, the "Query List" doesn't currently support error handling, meaning if an error occurs the workflow will fail. Having error handling like available for the "Execute SQL" and "Copy to SharePoint" actions will mean the workflow can be designed to manage Query List errors gracefully.

It would be a really great feature if you could implement a "Try" and "Catch" block action for trapping errors. The current error catching implementation only allows you to catch errors on certain actions. Having these as drag and drop actions on a workflow to encompass other actions would be a great way at pinpointing where errors occur.
