Based on a question in the Support Forum I have added a new feature to suppress breaking a form into multiple columns when the browser is narrower than a specified width (e.g. on a phone). This should allow forms which are set up for columns to be presented better on phones and tablets.
If you’d like to try out this feature, download this beta release and provide feedback on any issues. By default, the plugin will handle columns exactly as it always has.Google Forms Beta (457 downloads)
