# TODO: would be nice to have monitors' workspaces show up in left-to-right
# order as laid out in physical/pixel space
# this would make glancing at the workspace indicator more intuitive
# TODO: might be nice to exclude certain windows as counting towards "occupation" such as xwaylandvideobridge or w/e
# NOTE: maybe I can group workspaces by their monitor with some mechanism for "unassigned" workspace to show up by a "primary" monitor
