It's great that many websites that have a huge list in pagination that lets user jump to specific page without tediously going 1 page at a time (as well as showing the last number to get to the end without having to “scroll” through the numbers).
This would be great for forums, sections, and pretty much anywhere when there are a lot of content that would make the page number such a large value, that way, I can jump to any number, say 200, without having to pick the closest number, and try to “scroll” through it until it appears on the page list number.

No-one will probably bother doing that so here's a workaround you can try: Go to page 2, then find something that looks like "page=2" in the URL and change that to the page number you want to go to. If you really want then you can create a Tampermonkey script that will add a box like what you described.
