Fedora 22 (GNOME 3.16) introduced this expandable legacy icon bar in the bottom-left corner of the screen:
As you can see, even when closed it takes up a few valuable pixels in the corner (where I am usually looking, when using a terminal). It also annoyingly expands whenever my mouse cursor ends up on top of it.
How do we move or disable this thing?
Best Answer
Try the GNOME shell extension TopIcons. This moves the legacy tray icons shown in this bar to the main GNOME bar, up in the top right by the menu.
