Hi Vibha / Dan,

The way it works:  it searches for the first "hatnote" in a page, which usually contains a disambiguation link, and transforms it into a "Similar titles" button, but *only* if the hatnote contains a single link.

What this implies:

- Hatnotes with more than one link will not be transformed (e.g. https://en.wikipedia.org/wiki/James_(name) ).

- Only the first hatnote is transformed (e.g. https://en.wikipedia.org/wiki/Santa_Claus ).

And here's the APK:
