I was watching a YouTube video (around 2 hours long) when I noticed something annoying: I kept moving my mouse just to check how much time had passed.
It’s such a small thing, but it kept breaking my focus. And honestly, it felt ridiculous that there wasn’t a simpler solution for this.
So I built one myself.
What I Built
I created a Chrome Extension that shows the current timestamp as a persistent overlay in the top-right corner while watching videos in fullscreen mode.
No mouse movement needed. No interruptions. Just always visible progress.
Shortcuts
-
Press
Y→ Toggle the overlay on/off -
Press
Shift + Y→ Change the overlay style
Why I Built It
This wasn’t some big product idea. It started as pure frustration:
- Watching long videos
- Constantly moving the mouse just to check progress
- Breaking immersion every time
So instead of tolerating it, I built a fix in a few hours.
⚙️ Simple, but Useful
It’s not complex, but that’s the point.
Sometimes the best tools are the ones that remove a tiny annoyance you didn’t realize was draining your attention.
Now I can watch long content without constantly interacting with the UI.
