Since 3.7.1 it is possible to drag and drop properties in UBIK Studio. This feature is only available in the Class Browser. That means the property has to be dragged from the Class Browser and can only get dropped in a Class Browser.
The Drag and Drop detail window is on the bottom left. When a property hovers over a potential target, the related information is displayed in this window. If a Drag Drop Action is available a green icon with a title and a more detailed description will appear in the Drag and Drop detail window.
If no action is available a red icon will appear, together with a short title and a more detailed description next to it.
