- Isotope sorting by repo language
- Custom *language overrides* (if you don't like what GitHub assumes it is) and *custom avatars*
  - Defined in `custom-repos.js`

To Come
--
- Make sure responsive layout is perfect

Call for Help
-- 
- Create 40x40 repo avatars, then define them in `custom-repos.js`
  - These are only shown if there is also a homepage defined on GitHub
- Figure out a way to cache API results
  - Non-Oauthed apps are limited by IP. Other large brands don't do any caching and just let it fail.
