+1 for font size options. And don't skimp on the range. I'm not sure you can have a too-small option. HN is textually dense. That's one of the things that makes it nice - no photos, just people talking. Continuing with that feel is good.
Hey! So I released an update today which adds settings to change the font size for story title, text and metadata.
There will also be another update tomorrow available which will also add ability to edit the padding around elements to make it as compact as you like which lets you see more content on screen. Check out the screenshots of what it would look like after tomorrow’s update (note that all sizes will be fully customizable to your liking):
