Change how stations are displayed so they're not in a regular HTML select menu. Use some kind of custom JavaScript + HTML menu such that we can have more than plain text in each option.
Add a little heart icon next to each station. Grayed out or empty by default, filled in and Soma-red when the station is a favorite.
Allow clicking a grayed-out heart to save in local storage (or shared Chrome storage? wherever options are stored currently) that that station is a favorite.
Clicking a red heart should remove that station as a favorite.
List favorite stations alphabetically before non favorites.
As requested in #19.
