Improve drag between columns UX

[artfulrobot]

Is your feature request related to a problem? Please describe.

I find it very difficult to move cards between columns. This is because you have to drag right to the very edge of the screen - so much that your finger is hardly on the screen and has to push the phone case aside. Then, if you get it to trigger a move, it does several at once!

Describe the solution you'd like

I think the entire point of hold-drag is to make an enjoyable, easy ux.

I think it would be improved by:

• visible, wider side zones that trigger a column move
• more delay/repeat between columns
• perhaps allow dropping onto the column header name, too.

Describe alternatives you've considered

You can move an item through the menus but it's a lot of tapping.
