Okay, I came up with an idea I think most people will like: the option to change how many posts are shown on each page. I believe there was an option like this on the old forum, and I think it would be useful to change how many posts are on a page. The default would remain 40, but there would also be options for 20, 100, 200, all, and other numbers.
I could have sworn I saw the option to change these type of settings on here before; and not just the archives. Yet, now I can't find it. Odd; I'll keep looking, but I would support this, even if it was only like on the archives, and didn't take long to implement.
