Do you want to move the GNOME Shell default hidden bottom-left system tray to the top-right on the top panel? If so, then TopIcons Plus extension by phocean is for you. This will make any of your tray application shows its icon always on the top panel.
Install
Follow our tutorial about installing GNOME Shell extension. Once installed, you will find a new entry in your GNOME Tweal Tool program and you will find any running tray application (such as Telegram, Hexchat, Shutter, or anything else) sits on the top panel.
Default Tray Position
This is the default GNOME Shell tray position on the bottom-left of the display. It is hidden by default and needs more clicks to show or to hide. We will change this.
TopIcons Tray Position
These are the same tray icons but on the top panel. By achieving this, every icon will never be hidden anymore.
