* Let’s start from the biggest to the smallest:
*
- * - An i3Screen is a virtual screen (Xinerama). This can be a single one,
- * though two monitors might be connected, if you’re running clone
- * mode. There can also be multiple of them.
- *
- * - Each i3Screen contains Workspaces. The concept is known from various
- * other window managers. Basically, a workspace is a specific set of
- * windows, usually grouped thematically (irc, www, work, …). You can switch
- * between these.
- *
- * - Each Workspace has a table, which is our layout abstraction. You manage
- * your windows by moving them around in your table. It grows as necessary.
- *
- * - Each cell of the table has a container, which can be in default or
- * stacking mode. In default mode, each client is given equally much space
- * in the container. In stacking mode, only one client is shown at a time,
- * but all the titlebars are rendered at the top.
- *
- * - Inside the container are clients, which is X11-speak for a window.
