I personally left using Ubuntu since they introduced Unity. I didn’t like the lack of customization in it. Since then Unity has come a long way and it gained some serious performance improvements over the years and many people started to like it. I still don’t use it but I’m happy to write about a long awaited feature: users are able to move the launcher to the bottom starting from Ubuntu 16.04 LTS.
Move the Unity launcher to bottom / left
Move the Unity Launcher to bottom
gsettings set com.canonical.Unity.Launcher launcher-position Bottom
Move the Unity Launcher to left
gsettings set com.canonical.Unity.Launcher launcher-position Left
