Regarding the font size, it doesn't use the system wide font size because during my testing, I found it wasn't reliable for the custom fonts as the same size would look different for different fonts. I will include a way to change the font size in an update (either tomorrow or the next one, I need to see how much change I will have to make in the code). I will add it in.
+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):
