Due date in Milestone/Tasklist View

Due date in Milestone/Tasklist View

Zoho is one of hart of my company, thank you so much to make this solution.
but I just want to one change, that is due date change issue. 

Now we can only change due/start date when we are making new tasks, 
otherwise we have to go to task detail view if we want to change the date.
Why can't we change due/start date when we are at milestone or tasklist view.
please change it ASAP
