Each time you open or select an already open application, you need to point the mouse to the upper left corner, which is quite a bother.
Ubuntu 14.04 Gnome comes with tweaks (the system is named: Optimization tool), can make the interface like Windows (Minimize, maximize, bottom taskbar, etc.)
If it is not possible to install with apt:
sudo Install Gnome-shell gnome-tweak-tool
There is also an extension called the Dash to dock , which automates the application menu on the left, official website: https://micheleg.github.io/dash-to-dock/releases.html
First look at the Gnome shell version and then choose the appropriate version to download (Gnome Shell 3.10.4, so I downloaded version):
Gnome-shell--version
The extracted files are placed in the~/.local/share/gnome-shell/extensions/下,然后 Alt+F2 输入 r, 重启 gnome,就可以在Tweaks extension中看到 Dash to dock 的选项,启用即可。
