There is also a new option to show a few line excerpt of the story cached text or summary text in the main story lists. This was requested a few times. Helpful on the mobile view to avoid a click, I suppose. Feedback welcome on whether it should be bigger, smaller, faded, etc.
Submitters can now select a “I am the author of this story” option when submitting to make it clear they are the author of the text, for follow up questions or flames.
And finally, comment trees can be collapsed to ignore a conversation going off topic or whatever.
