Backstory: YouTube creators constantly say "don't forget to like" – and I kept forgetting. I wanted a simple way to automatically support channels I follow without thinking about it every time.

What it does: - Whitelist channels → auto-like their videos - Blacklist channels → auto-dislike - Timing options: instant, after X%, or after X seconds - Optional "humanize" mode adds random delay

Technical notes: - Manifest V3, minimal permissions (storage + activeTab) - All data in chrome.storage.sync, nothing leaves your browser - No analytics, no tracking, no remote calls - ~500 lines of vanilla JS

Chrome Web Store (no signup needed): https://chromewebstore.google.com/detail/youtube-auto-like/n...

This is my first Chrome extension. Open to feedback on the code or UX.
