Appointments+ Overlap, Help Removing Column

Hello WPMU Dev Team,

Thanks for making this plugin it has proved quite useful over the last few months.

I am having a bit of a problem with the date picker overlapping the right side of my content box. So on devices with smaller screens it doesn't look very nice.

I am looking to remove the Sunday Column since it is not used as a working day. What is the best way to go about doing this?

Thank you for your time,

Robert Zamida
