Drag and drop for mobile apps

Its so much easier to organise when we were able to drag and drop tasks within each day and to other days and boards. I want to be able to organise my day as I go by switching the order around effortlessly and alot of the tasks have no time. Why was drag and drop taken away? 

I recommend you look into the bullet journal model it will be very useful in this app. 

Also it was helpful when we could always see a list of unassigned tasks at the bottom of the week which I was able to drag and drop to specific days. So a this week list that hadn't been scheduled yet.   Thank you
