But is that something that should be in this config?  I would think
that would be something done on a window-by-window basis, rather than
a system-wide setting.  I see two possible ways to handle this (not
mutually exclusive):

1. A window rule to ignore multi-monitor information when maximizing.
2. An option when right-clicking on the title bar to maximum ignoring
multi-monitor information.
