The URL for my blog main page is /blog. When you dig deeper into the blog and get to page 2, the URL changes to this messy ending: /blog?447f3997_page=2. I can see value for leaving the page=2 in there, in case you wanted to direct someone to a specific post that's on page 2, but I'd like to remove the 447f3997 mess. Generally speaking, I would just like the ability to customize or modify the URLs on paginated collection pages.
