About

Visually highlights the root message of the currently open thread in the center channel. Never lose track of which conversation you're reading.

Features

- Active thread highlighting — when you open a thread in the right-hand sidebar, its root post in the center channel gets a subtle amber border and background overlay
- Configurable domain — works on any self-hosted Mattermost instance, just enter your domain in the popup
- Instant detection — uses MutationObserver for immediate reaction to thread changes, with interval polling as fallback
- Zero reload apply — changing settings takes effect immediately without page refresh
- Lightweight — no external dependencies, minimal DOM footprint, pointer-events passthrough

Fixes:
- Fixed thread highlight appearing with a ~5 second delay after page load for Chrome Web Store users
- Improved extension responsiveness by optimizing how DOM changes are detected
- Fixed extension not working after browser restart without reopening settings
