I am currently using a project plan view and have a number of sub-items for an activity for which I just need to track status. Once it is done, I no longer care about it.
For my main board, I have a filter to ignore where the “Status” is not “complete” and then hide those items. This helps me with real-time reviews to only focus on work that is still outstanding / pending. When I look at subitems, I unfortunately do not have this same luxury as the filtering does not apply to subitems. In my actual working project, I have one task that has 73 subitems that I am tracking against. Roughly 45 of the subitems are done, some are in progress and others are not started. What I am hoping for is the ability to filter out the completed subitems so I can reduce the noise for real-time reviews and focus the team on what matters most for the project.
