I was watching a long YouTube video (like ~2 hours), and I kept doing the same dumb thing:

Move mouse → check timestamp → move mouse away → repeat every few minutes. It’s a tiny thing, but it kept breaking focus, especially in Fullscreen. So instead of accepting it like a normal person, I built a Chrome extension for it.

What it does

It shows the current timestamp as a persistent overlay in the top-right corner while you're in Fullscreen. No mouse movement needed. It just stays there.

Shortcuts

• Press Y → toggle overlay
• Press Shift + Y → change style

That’s literally it. No settings, no setup.

Why I made it

Not a startup idea. Not trying to “disrupt video consumption” or whatever.

Just got annoyed enough to fix it.

Tech (if anyone cares)

• JavaScript
• Chrome Extensions API
