We are writing an app that manages workflow processes. Users needs to be able to identify which task have been updated since their last log-in and which tasks require their input. The tasks are listed in a grid. There is also the added complexity of the tasks being updated by other users while the user is logged in. What would be an intuitive way to keep the user informed of the state of tasks?
I was thinking of using a orange dot next to tasks that require their input and bold-ing the text for tasks that have been updated since the previous log-in.
