Dash to dock
Mailnag (with the Mailnag App)
Manjaro linux updates indicator
Places status indicator
Removable drive menu
Remove accessibility (Because I have to increase fonts size on my FHD display.)
I used to have OpenWeather, but not needed anymore with the weather now shown in the Notifications/Calendar. You still have to install Gnome Weather for it to work.
On a side note, if you’re on a laptop and prefer to use the touchpad. libinput-gestures is a game changer. https://github.com/bulletmark/libinput-gestures/blob/master/README.md
I use Adapta GTK & Shell theme and La Capitaine icons theme.
