I used the web version and noticed it said it was "for showcase only." How is it different from the other builds? It might be good to add this to the description.
A few other things I noticed in the web version:
The ' character seems to be treated as quotes, I think? So if I write "I don't know" then "t know" (everything after the ' -- even on new lines) is colored differently until I use a ' again. This is a little odd when using it for non-programming language, in contractions (like "isn't" and "it's"). The " character is not treated in the same way.
Also there doesn't seem to be recognition of any hotkey for jumping between words with left/right arrow keys (option on mac, ctrl on pc). I don't think I tried Home or End though.
Thanks for sharing!
