1. Would be great to have some facility to save the links across browsers/devices so that this is not lost on reinstalling browser or switching device. May be by upload to user's own Google Drive or iCloud account - so that doesn't cost you storage cost.
2. Right now, I see it's working only for the homepage links, and not for other discovery pages such as https://news.ycombinator.com/newest or https://news.ycombinator.com/ask or even https://news.ycombinator.com/front. You can find the official lists here : https://news.ycombinator.com/lists . Would be great to support these.
3. Would be good to have the source code available - to give more confidence on the plugin as well as others can improve on it.
4. Checkbox at the start is distracting - can it be put at the end of item line or having option to customize would be good.
More power to hacker news developers.
I've already addressed items 2 and 3. An update is under review on the Chrome Web Store and I've put the code on Github: https://github.com/arnipluseinn/Hacker-News-Saver
The other two items on your list are going to need some more thinking/work.
