How to put "By Appointment Only" or some other such text instead of time slots?

Hi laurendevine,

there’s currently no option covering this. A quite dirty solution (but should work) is to agree on a specific start and end time of a period, that will later on be replaced by your string.
To do this, use the filter op_overview_widget_time_string and do something like:

add_filter( 'op_overview_widget_time_string', function ( $timeString ) {
  return ( $timeString == '01:00 – 01:01' ) ? __( 'By appointment only', 'textdomain' ) : $timeString;
} );

Then you will have to set one period with 01:00 to 01:01 on the weekdays you want to show the message on.
Mind that the string depends on the date format settings you have made. So you better set these specific hours before adding the filter, and then copy/paste the time string from the overview table into the filter function.

But this solution is indeed not very dynamic. I’ll try to implement more powerful filters in the next version.
