Go to Easy Timetable main screen thru Joomla Menu "Components -> Easy Timetable"
The Dashboard proposes three blocks to have on overview of your timetables and activities.
The "HOW TO" block is a little reminder of the process of building Timetables.
You will be able to create new activities and new timetables from this screen (by clicking on the "+" character) and editing existing ones.
The "Options" button let you manage global access rights for the component and jQuery loading script options.
