Auto Search Feature

I decide to start a UX experiment project: tiny UX.
The goal is to improve user experience by doing small tweaks on design.

Here is the 1st shot:

We all like the small pop-over when texts are selected in Medium's articles. What I do is adding one more tiny feature here: auto search all related article headlines which could be a context. You can easily turn it off by clicking the toggle in the pop-over.

Don't forget to check the attachment to see more details.

Let me know your thought:)
