react-dnd doesn't work with touch screens #50
Description
Options:
- Add react-dnd-touch-backend or, better, give users the option to install it themselves and pass it to the context.
- Once Make dnd optional #17 is merged, force the no-dnd mode: the advantage of this is that we could get rid of the select field column and use the schema preview column for both the schema preview and the property editor, this way we only need two columns which is easier to integrate in a mobile UI.
