To enable this feature add `workspaceHisotryHook` from
`XMonad.Hooks.WorkspaceHistory` to your logHook.
Your previously-visited workspaces can be navigated with
the 'moveHistBack' and 'moveHistForward' actions (which are bound to the 'o' and 'i' keys)
TreeSelect displays your workspaces or actions in a Tree-like format.
You can select the desired workspace/action with the cursor or hjkl keys.
This module is fully configurable and very useful if you like to have a
lot of workspaces.
Please see the Documentation provided by 'XMonad.Actions.TreeSelect'.
