This plugin solves the problem of when you have long pages/posts/custom posts edit screens in the WordPress admin, usually caused by lots of custom fields or plugins. Whenever you get down to the bottom of the page you need to scroll back up to the top to press the update or publish button. This plugin solves this problem by automatically scrolling the sidebar into view as you scroll the page.

Sticky Admin Sidebar

Simple, but very useful. Still works with WP 5.2 (you should SVN an update to the readme).
