Jump to Album or Artist Index
Similar to jumping to a specific letter when viewing Albums, add a jump to specific album index number.
When, for example, I go through hundreds of albums one at a time checking & updating cover art, I might need to stop at album index 500 of 800 and go do something else. At some point, I want to resume at album index 500 without needing to page around to get there.
The page numbers are in the URL, so you could copy and paste the URL, but the more albums you show at once the less useful this gets.
Hmmmm... also (and I _think_ this works) if you copy the URL for an album (the last one you edit) then go back to that later, click the "back to album list" link at the top right, this should put you back on the page with the album in. I think...
