Activity Bar width in Visual Studio Code

Question

Is there a way to selectively change the width of the Activity Bar in VSCode (v. 1.14)? I have a 1366×768 screen where every pixel counts, so I would like to make this bar narro

Wanted to add more to Akelian answer:

On Windows/Linux - File > Preferences > Settings
On macOS - Code > Preferences > Settings

{
  "window.zoomLevel": -1,
  "editor.fontSize": 13,
  "terminal.integrated.fontSize": 16,
  "workbench.activityBar.visible": false,
}

Setting false to "workbench.activityBar.visible" removes the sidebar completely
