Not sure is anyone said something like this, but would it be possible to make the text that links to a deprecated class appear with a -strikethrough-, a grey-ish text, a deprecated symbol next to it or something like that in the API page? So that way players at least get some form of an idea that it’s no longer intended in new work without having to click on it to see the deprecated message.
Other than that, it’s honestly not that terribly bad so far for a beta (at least, on desktop), and it’s easier on my eyes.
