In a recent past, I was using Unity, with Ubuntu 16.04. When I selected and opened a document in Nautilus, the display swap directy to the application corresponding to the document and this application was opening the requested document.
Now, with GNOME, under Ubuntu 18.04.2, when I select a document and ask for its opening, nothing happends. I need to swap manually the display the needed application, which was opened in the background, with Alt+tab. Worse, if a former document was openend by the same application, this first document is displayed, not the second one. I need then to swap manually furthermore to the second document with Alt+² Is there a way to improve this ? (Note that my opening preferences are double-click.) Thanks in advance.
