Mostly done now, except for some popups and tweaking. We have a top bar with dmenu launcher, 9 workspaces, window buttons, thermal monitor, graphs, battery monitor, wifi monitor, sound monitors, system tray, layout indicator, datetime, update counter and screen indicator. On the bottom is a debug bar (only shown when debug=true in config) which is pretty useless at the moment.
