There is some discussion in another thread on whether Attributes or comments tab should be shown first. I am in favor of Attributes. However we can have best of both worlds as under…
List item Add a setting ( project wise) for user to choose the default tab to open when a task is clicked - this will allow the flexibility for each user to match his individual requirements.
List item Would also suggest another tab for “Checklist” Attribute - these list can be long depending on the complexity of the task - and will get lost if with main Attributes. If kept separate , it will the user in following the process and % completion can be shown at top of the tab for tracking.
