There are some feature requests and bug reports on SN's Github repo:
From my observations, feature request are often first discussed in a Daily Discussion post. Or there's also the "stackers chat" Telegram group: https://t.me/stackernews where features or fixes can be discussed.
Then if warranted the feature is either noted for future implementation or reference, or implemented into SN is begun, or added to the Github Issues.
Also see what is not a roadmap for future updates, but the rear-view mirror for past updates:
