Love the Boutique. Oh, and listening to Linux Unplugged.
I just wanted to suggest swapping Redshift out in favor of f.lux gui. Seems like it has active development and keeps up with Ubuntu releases.

My reasoning is the color temperatures are adjustable in the indicator applet. Additionally, it doesn’t require geoclue to find location on your IP address. All you need to do is enter your coordinates or zip code and it sets your location.
Totally personal preference. I just always have problems with redshift acting funny when you exit the app and it never seems to reliably adjust when it starts up.
