Hi I just installed your plugin and I love it- great work!
The only thing I had the same problem as here http://wordpress.org/support/topic/plugin-appointment-calendar-booking-timesservice-duration?replies=9
But fixed it with a small fix.
But I can't find an option to add or just change Duration Unit types - I need it to be Hours instead of Minutes. While creating a new Services you have a drop-down menu for Duration Units, so there should be way to have different options there, or not?
Please advice me how to fix it or where to find it.
