Sorry but English is not my language.

In the beta version has appeared a great opportunity in the form of the day view.
Calendar of any organizer has this feature, because it is very convenient. Drag the event in the day view, thus changing the start and end time. You also need to add the ability to change the duration of the event by changing the size of the task (by dragging the edges), thereby altering its duration.

These are planned but I can't say when they are going to be implemented.

Thanks.
