Doesn’t work with hour intervals. Too complicated.

Plugin does not allow hour intervals to be selected properly. You can set up hour intervals (in a very complicated not user friendly way) but on the front end two click are required on the same interval to select just that interval. Basically a user can select one interval as the start time and a second interval as the end time. This makes this worthless if you need them to only select strictly defined intervals. The documentation is also very vague and doesn’t actually explain any of the settings.
