Input, a customizable font family (sans, serif, mono) for code

Strangely, it seems the HN search will exact match on the initial search and then prefix match after that. Compare URLs:
Initial search
https://hn.algolia.com/?q=input%20font#!/story/forever/0/input%20font
Add an 's' then remove it
https://hn.algolia.com/?q=input%20font#!/story/forever/prefix/0/input%20font
Same search term shows in the box, but the results are different.I've submitted an issue on GitHub to address this: https://github.com/algolia/hn-search/issues/41
But I found that I rely on intra line alignment often and proportional fonts cannot deliver that. The end result is so ugly as to completely overwhelm the advantages.
I ended up returning to M+.
