What's still missing is a list of posts at the side. So often someone mentions a post by someone else, and it's impossible to find that particular post, a search of the page is only a help, if the post itself is on the same page, otherwise you are hopping to and fro and in the end have forgotten why you were looking for that post after all.
Another site I am on has existed since 1999 and has always had such a summary list at the side of a thread so that you can click on a name and have a quick look at the previous post referred to. I suppose because it's a feature that is now nearly 20 years old, it is considered old-fashioned.
I'm not getting all this grey many have mentioned - neither on tablet nor on laptop. The big advance is that my own posts are now blue on the laptop as well as on the mobile devices.
