When you work on an Event Calendar, you want to show it perfectly organize and simetricaly visual. So a Justify colums elements option should be very interesting.

Also, it is very necessary to be able to personalize row numbers and add a navigation option ( arrows / numbers / dots ) or a "view more" buttom .

This would be very interesting if you have a extense events calendar but don't want to show it all once and make a visually shorter Div on your website.
