@Jaxel Hello,
What do you think xenevent premium version?
I want to suggest somethings about it.
24 hour time format can be very well or an option to choose 24 hour and 12 hour format,
I think you should remove "recur this event" section because generalley members cant use it. They open it and forget after that we must move recur option all event one by one.
You must make a alert system for event. For example we can set a remind time and your addon can send alert to members which is set answer Yes and Maybe on event.
You can make an option to set default google map location.
