This is nifty. Thanks for sharing!
I also got tired of waiting for http://baaqmd.gov to load each time I opened the page, so I bookmarked their air quality map on my website at http://mag.cm/air-quality. The direct link allows me to open the map in less than a second.
It would be extra neat if clicking on this app in the menu bar brought up the BAAQMD air quality map, but I suppose that would only be useful for people who live in the Bay area.
I was tired of constantly always going to https://airnow.gov/ to check the Air conditions in San Francisco, so I made this menu bar app that will let you know the air conditions in your zipcode.
