This function should be expanded to also handle blocks and images/files that are dragged into the editor.
@Episerver would be nice with a voting system so it is possible to vote on feature request in a proper way instead of commenting that you agree with the feature request :)

Could put a tooltip/title attribute on the "buttons"?
