Hi Eran, first thank you for this great plugin. I work for a non profit organization, but we interested to pay something for some extra functionalities if you are agree with the idea:
1- limit the time range to a day event only.
2- limit the daily schedule only for 2 events in the morning and 2 events in the afternoon, 3 hours block each one. After that sum users couldn't add new events in a day.
3- hide Repeat option in the new event form
4- possibility to add fields in the new event form, same way like "Contact person", but with the name "Assistants".
5- add an event status only editable by admin.
