Sidebar System

The Sidebar System can be used to display a dynamic array of buttons on the inventory screen as shortcuts for the user. Many FTB Mods add one or more buttons to the sidebar by default.

Editing the sidebar

Right-click a sidebar button to enter edit mode. In edit mode you can:

• Drag buttons to move them.
• Click the small x on a button to hide it.
• Click the + box to add hidden buttons back.

Right-click again, or click away from the sidebar, to leave edit mode.

The gear/cog button opens the client config, where you can turn the sidebar off or change its position.
