+Module groups allow stacking modules in the direction orthogonal to the bar direction. When the bar is positioned on the top or bottom of the screen, modules in a group are stacked vertically. Likewise, when positioned on the left or right, modules in a group are stacked horizontally.

+    <description summary="list and control workspaces">
+      Workspaces, also called virtual desktops, are groups of surfaces. A
+      compositor with a concept of workspaces may only show some such groups of
+      surfaces (those of 'active' workspaces) at a time. 'Activating' a
+      workspace is a request for the compositor to display that workspace's
+      surfaces as normal, whereas the compositor may hide or otherwise
+      de-emphasise surfaces that are associated only with 'inactive' workspaces.
+      Workspaces are grouped by which sets of outputs they correspond to, and
+      may contain surfaces only from those outputs. In this way, it is possible
+      for each output to have its own set of workspaces, or for all outputs (or
+      any other arbitrary grouping) to share workspaces. Compositors may
+      optionally conceptually arrange each group of workspaces in an
+      N-dimensional grid.
+
+      The purpose of this protocol is to enable the creation of taskbars and
+      docks by providing them with a list of workspaces and their properties,
+      and allowing them to activate and deactivate workspaces.
+
+      After a client binds the zext_workspace_manager_v1, each workspace will be
+      sent via the workspace event.

+
+        This allows changes to the workspace properties to be seen as atomic,
+        even if they happen via multiple events, and even if they involve
