When recieving a task in a running workflow, there is a functionality to enter a comment before the task get finished by voting or completing. After Vote and complete a tasks the comment will be visible in the task list.
However if the task is not yet finished but the assigned user wants to store an information such as: "waiting for feedback from ...." you have to open the task in order to see the saved comment. Its not visible in the task list.
When processing several hundreds of tasks a week, it would be more than good to see the added comment in the list instead of the need to open every active task.
Since the Data is stored on BLOBS its not directly accessible by the GUI or from within a report.
