Currently, you have the ability to rename Task Groups easily within the plan view. I think it would make sense to also be able to rename Tasks from this same view without having to click into and expand the Task to edit/save.
Often times when stitching in a new task group, we would like to update the names. E.g., when stitching in a "Revision" task group, I would like to be able to quickly rename some of the tasks to include "#2" or "#3", etc., not just the task group name.
Another case would be when adding a new task to a project, if there is a misspelling, it would be useful to be able to quickly rename it from the plan view without having to open the task, rename, and then refresh to see the change.
