An easy and elegant way to use your computer, GNOME 3 is designed to put you in control and get things done.
gnome-control-center: is the basic environment configuration GUI
From here, you can type to search for anything. In this case, we would type "gnome control center" or just "settings". To open it, simply click on it with your mouse or just press Enter on the keyboard.
For the configure the Gnome Shell behavior and look and feel, we get gnome-tweak-tool:
Gnome Tweaks are mostly for enhancing the look and feel of the Gnome Shell. Appearance: Theme settings The Global Dark Theme switch allows for themes that provide this option (like the default Adwaita) to global enable the dark look also for gtk2 apps, if youn have a theme with a dark look itself it will mostly have a gtk2 dark setting inside. To get Shell Theme working you need to enable user themes inside Extensions. Extensions:As GNOME always does, it simplifies everything, if you want to customize certain things, the extensions are probably the place for it. Fonts: On modern displays you will need to put this too slight or None and Rgba. Startup Applications: very usefull to autostart apps you want too.
Gnome shell extensions:
Remember that there are two ways to get extensions installed.
1: over package management, this ones can not be removed inside gnome-tweak-tool and also updating is only possible over package management.
2: gnome shell extensions internetside https://extensions.gnome.org , needs only the package chrome-gnome-shell zo be installed for chrome based browsers. Installing extensions over this ll make you able to remove them from gnome-tweak-tool and updating them over the website.
