HOW IT WORKS
When an author link scrolls into view the extension queries the Arctic Shift API ([https://github.com/ArthurHeitmann/arctic_shift](https://github.com/ArthurHeitmann/arctic_shift)) to retrieve that user's top subreddits by activity. A huge thank-you to Arthur Heitmann and the Arctic Shift project for making this data openly accessible — this extension would not be possible without it.
NOTE ON ACTIVITY COUNTS: the count shown on each pill represents COMBINED POSTS AND COMMENTS the user has made in that subreddit during the configured time period, not posts-only.
