I totally agree. One thing though with the calendar plugin is that there is a long list of features that everyone wants and even such a “looking easy to implement” feature as this one may take time before being implemented(not blaming the devs, its great we have so much for free already).
However to remain solution oriented here I thought of a little hack (not saying I will do this script but here it is) :
-Devs were kind enough to set up a custom field that retains a value, you may with Javascript change it to an all day checkbox and bind an event that when the checkbox is checked, it sets the time of event from 00:00 to 23:59 and hides the hours fields directly.
I use it just use this field for showing the max participant of the event until the max participans feature is available.
By the way you said
our members may believe the event is actually starting at 3:00am their time under our current work around.
I’m curious, what’s the work around that generates this situation?
