Gmail Labels and Filters

In honour of the new year and fresh starts and whatnot I deleted all my gmail labels and filters and started from scratch. I'm terribly proud of the results needed to share:

I used nested labels for the first time and like them so far! The "KEEP!" label is for junk like airline frequent flyer numbers and library card numbers and cell phone serial numbers. The rest is pretty self-explanatory.

I also love the easter-egg-y color scheme. I need some purple in there though. Pretty!

I'm not done yet and likely need more labels. What am I missing/forgetting?

**update** The nested labels look great on my Android too and are denoted by a "/" following the larger heading i.e. Money/ENT
