Yes, I wanted to build something that my students using Windows or Mac OS also could easily use. And I wanted to build a web extension for Firefox and Chrome using the same format. And maybe integrate it in some other tools we're using here as well. Of course, that was too ambitious and the only thing I ended up with was an integration in vim. And that could have been done easier, as your sibling posters have pointed out. Anyway, it was fun to build and very useful the past year.
