[Feature] Hover event element

[alezzigo]

Before selected one target, can fire hover event target? Thank @daybrush!

It seems difficult to provide hover events. What about providing a property representing hovered elements in the drag event?

It may be that when no element is selected, hover can be provided to view the currently selected element?
