Advance Title Search maneuvering difficulties

Advance Title Search has become one of my favorite things about IMDb, but I am having problems maneuvering though, and back-and-foth within the listings. With long lists of titles, it is very difficult to move back and forth. The “add 50' in insufficient and time-consuming. Before, the first page was 1-thu-50, the second 51-thu-100, etc., and one could easily move from page to page, and even “jump sound” by altering page numbers in the URL. Now, each “fifty” is just added onto the previous fifty, which can add up to many additions when maneuvering an ever-increasing list of titles. The previous programming was much easier to utilize. Also, when one hits the back arrow to go to the previous page, you are not sent to the previous fifty, but to the middle of the first fifty listed titles. Is there a way to “go back” to the 1-50, 51-100, etc. pagation, and to the backward arrow going to the previous page rather than the middle of the first page. Perhaps this has been discussed elsewhere. The current programming is very annoying and certainly interfers with contributing.
