compare branches: show all option

Summary

Since the last(?) release comparing branches now doesn't show all changes, but splits it in pages of 20(?) results.

Steps to reproduce

Compare two branches with a substantial enough difference.

Example Project

What is the current bug behavior?

There is no "show all" button or option (not even a per_page query option)

What is the expected correct behavior?

A way where i can load all the changes in a single page so i can ctrl+f filenames and keywords without having to repeat it for all of my 4 pages just to find something again.
