List views are Horizon pages that enable you to display a list of records for an object, according to your needs. These UX improvements have been applied to all screens in the web app that use the Horizon list view, including custom list views and standard lists, such as the User roles settings page. 

There are two main improvements:

1. You can now "freeze" the first column of a list view to always have it visible on your screen; no matter how wide your list view is. This is useful for list views that have many columns and a horizontal scrollbar present.

Simply enable this option by clicking "Columns" on any list view page and select the "Freeze first column" checkbox. This will fix the first column in place, no matter how far you scroll horizontally. 

2. The footer and header of the list view are now always fixed in place and visible. This means that no matter how long your list of records is, you'll always have access to the list view action buttons, the list view column headers, and the list view pagination tools. 

This makes it easier and faster to select items in the list and easily see the corresponding column header, as well as perform any single or bulk action on the selected items.
