Overview
A browser extension for Chrome and Firefox that gives you an instant vibe of who's commenting. It displays coloured split-pill badges next to Reddit usernames showing their most active subreddits — visible at a glance without leaving the page.
Works on both WWW.REDDIT.COM and OLD.REDDIT.COM.
---
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.

FEATURES
* SPLIT-PILL BADGES — each badge shows [subreddit | count] with distinct background colours for the subreddit name and the activity count.
* ALL SUBREDDITS — not limited to any specific community; shows whichever subreddits a user is most active in.
* SORTED BY ACTIVITY — pills are ordered highest-count first.
* CLICK TO SEARCH — clicking a pill opens an author-scoped subreddit search (/r/SUBREDDIT/search?q=author:USER) in a new tab.
* VISIBILITY DETECTION — only processes links currently in the viewport; new content loaded by infinite scroll is picked up automatically.
* DE-DUPLICATION — already-labelled links are skipped; concurrent requests for the same username are coalesced into one.
* RATE-LIMIT HANDLING — respects x-ratelimit-* headers; shows a clickable retry badge when paused.
* 1-WEEK CACHE (CONFIGURABLE) — user data is cached in chrome.storage.local and only re-fetched after expiry.
* OPTIONS PAGE — configure API parameters, pill colours, cache duration, and pause/resume the extension without reloading the page.
