Some minor changes to EventOn (a wordpress plugin)

EventOn It's an event calendar plugin for WordPress. The plugin has already been modified for specific purposes but I need some minor changes to EventOn itself and to one of its addons (csv importer). It would be useful to know already how the plugin works... 1. I need to change the default values for some editable settings. These values can be changed in every single "Event Page", when you edit (o create) a new item. This is how they must be set: Hide End Time from Calendar -> on Hide Organizer field from EventCard -> on In other words, the "Ending Time" for every Event must be hidden by default. And the Organizer Tab must be hidden too. 2. The possibility to add the "Event SubTitle" column within the CSV file itself. Otherwise you can add it only when you edit (or create) a new Event.
