When creating or updating a workflow, the validation testing is super helpful for finding various issues before publishing.
However, because the window holds focus we don't really have a way to reference it as we address any identified issues.
As a result, I usually end up using the snipping tool to grab a screenshot when there's more than one issue.
What would be helpful is an option to display validation at the bottom of the workflow tab, similar how Visual Studio shows errors/warnings.
That way, I could see validation issues listed at the bottom of the designer window for easy reference as I make the necessary corrections.
This would also make it easier to have features like clicking on the error to auto-select the affected activity without dismissing/losing the dialog.
UPDATE: Edited the last statement for clarification.
