We struggle with the current Life After Death settings because we do not want people to be able to add new tasks, change dates, or change assignments, but we need them to be able to edit the custom forms that are on tasks. Currently, the only way to do this is to activate the setting which allows tasks to be fully edit-able after the project is complete. This is also inconsistent with how it works on project themselves, as project-level custom forms can be edited after the project is completed without having to turn on any settings. We believe custom forms at the task-level should be the same way, or to have a setting which allows for it.
It might also be beneficial to allow certain users or groups only to make modifications after the project is complete. In our case, it would be beneficial if Finance and Accounting had access, but we don't want any of the workers to be changing their task data.
