Orange Juice
If you don't mind me sharing ideas that I would love to have in such an extension:
- Changing the UI of the comment actions to make them easier to use. Using HN mostly on a phone, I keep hitting downvote when I mean to do the opposite. Similar with the collapse action.
- Keep a local list of users that get their comment subtrees stripped out. Some people are argumentative by nature and not in good faith. It's best to ignore them (easier when you don't see their comments).
- Hide new accounts by default (perhaps auto collapsed).
So far, desktop is the current target. Not even sure I can run extensions on a phone.
The last two fall under content moderation. I'm a bit less interested in that as it changes the UX and there are infinite things we could do there. Right now, the extension has no preferences switches, and I'd like to keep it that way for as long as possible. When there are a whole bunch of knobs to tweak, it makes everything overwhelming.
On the mobile extension side, just in case you were unaware, Firefox on Android has had extensions now for 2+ years.
Good luck with the project!
