The recent update actually looks very good and the interface is a big improvement on how it used to look, however they removed all the original templates that were the reason I liked the plugin (which, being their project, is their prerogative).
In keeping with the Open Source spirit, I simply forked the code for the plugin and rolled it back to the last point before the templates were deleted. For anyone else that liked the old templates, feel free to grab the old version from GitHub here: Caffeinated-Maintenance-Mode.
