Visual queue, in addition to workflow message

[lnguyen]

In a short workflow, this might not be necessary as the information related to each tool is spelled out in the progress windows.  However, in a complicated and lengthy workflow, tracing such msg can be a tedious task. In addition, using a tool with multiple outputs and only one output is selected while the residual outputs may be used to validate the result in the selected output; for example, joint tool where left or right output should be zero, a visual queue could be a quick way to alert operator on any potential problem.  Certainly, a browse tool can be added but in a big workflow, couple with a large data set, it might be a drain to the system resource. What if there is a tool that would activate a visual alert, like a light bulb, based on a preset condition to tell user that something is wrong and perhaps additional work needs to be done to either remedy or to account for the residual data. As in the case of a joint where 100% match is desired, any unmatched row would require an update to the reference list which maybe an additional adhoc process outside the current process. Certainly, an additional steps can be added to first explore the possibility of unmatched data and to update the reference list accordingly.  The workflow would in hold until 100% match is achieve. This would require additional system resource in order to hold; especially with large set of data and lengthy workflow.  If the unmatched situation rarely occurs, just a lightweight visual queue that 'pop' while allow the process either to break or to go through might be a sensible solution.  Just a thought.
