Make ubuntu more beautiful and better to use. Here contains many ubuntu theme and icons and many other setups. But only from my aesthetic.
First install tweaks tool first:
sudo apt-get update
sudo apt-get install gnome-tweak-tool
the best theme I know from now is gnome-osc-themes, you can find it at:
https://github.com/paullinuxthemer/gnome-osc-themes
Clone it and mv the theme into /usr/share/themes, then you can found it in Tweaks tool.
Install gnoeme shell extensions:
sudo apt-get install gnome-shell-extensions
Then open tweaks, you can open extensions tab, open the ubuntu themes taggle. (If not found, reboot thesystem)
From application center install dash to dock, just search and click install, you will get a dock.
Just inside SetWallperper you can run ./install.sh, it will install wallpaper for you.
