IMHO the notifications in GNOME (3) are hidden very quickly. Of course, it depends on the user, how fast he/she can read that notifications or so. So is there any way to change how long the notifications are displayed before they are hidden?Quickly searching through dconf I could not find any setting for this.Cross-posted from Ask Fedora.
