Drag n drop parent in timeline view

You can create parents in events by dragging and dropping them in the left-hand side bar, or by setting a parent event in the inspector. It would be convenient if you can drop an event into another in the timeline view too.

To prevent accidentally creating a parent-child pair, you can do maybe a key you have to press or a setting that locks creating parent-child in the timeline view, either for all events or for certain events only.
