Upcoming tasks seems to always be a mess for me. Sometimes tasks get pushed too far when dropped into upcoming and they get forgotten about or 20 task move into the tommorrow tab all at once.

I recommend small tabs that only pop up above or below the upcoming title when when you start dragging an item. When dropped the task will still appear in the upcoming column but simply have its date adjusted. this would be a big timesaver compared to going into each task individually and editing it there.

Tabs could be 6 days after tomorrow
this would allow fast & adequate planning at the weekend for the upcoming week, not just today and tomorrow. It will also be faster than using moment and going through all tasks

Otherwise I'm a huge fan of the app, great job guys!
