Switching between 6 and 12 months
If you are looking for a biannual view you can tap the 6-month-button at the top of the screen. Now the formerly small events are more accessible.
Creating a new event
There are two different ways to create a new appointment within the view. First you may use the add-new-event-button at the top right of the screen. In the second place you can click on a specific day to open a small pop-up-window. This pop-up comes with a tiny plus-button. Clicking it will open the input mask for new events. Finally you can use the FAB, to add new event/task, if set accordingly up.
Editing an event
To edit an event just look for the event you want to modify and tap the corresponding day. In the pop-up-window perform a long-tap on the event and the edit screen will open immediately.
