*Data Explorer*  is a panel that allows the user more interactions with data. Some functionalities provided by the Data Explorer are also available through the context menu of plot panels or other menus of the applications.Under menu *View*  of the menubar, Data explorer can be toggled between Show and Hide by clicking the menu *Show/Hide Data Explorer* .

*IMPORTANT!*  When Data explorer is hidden, all the data loaded will be sent directly to the current active application, if possible. When data Explorer is shown data go first to the Data Explorer for the user to handle them later.
