I know iOS has extensions, but in Yosemite, there are now extensions.
As you can see they are a number of them in the SysPref pane. The question is, where can you download them? A google search only shows these outdated Safari extensions, and AFAIK they are supposed to be a big component of new programs like Photos, allowing them to bridge the gap between pro users and amateur users.
