Views infinite scroll allows you to load and display pages of any view inline, using AJAX (this has been called infinite scrolling, load more, autopaging, endless pages and more). The pager can be triggered with the press of a button or automatically as the user scrolls to the bottom of the view's content.

The Drupal 8 version of Views Infinite Scroll is a lightweight solution which:

Works with the existing views AJAX system, no 3rd party libraries required.
Works with AJAX exposed filters.
Can be enabled on any view (block, page or otherwise).

Pagerer is a module providing a collection of pager themes to enhance Drupal and Views standard pagers.

Administrators or site builders can preset multiple pager configurations. Each 'preset' allows a pager to be made up of three 'panes': left, center, and right. Each pane can contain (or not) a pager theme. In this way there is plenty of possibilities to combine different elements to satisfy complex requirements.

Options Element is a module that provides a better mechanism to specify select list, checkbox, and radio button options. Rather than requiring the user to use strange syntax like "key|value" in a textarea, Options Element provides a clean interface for specifying options. Developers may use $element['#type'] = 'options' in their own modules. If JavaScript is disabled, any 'options_element' will degrade to the standard textarea for specifying options.

Provides a new Forms API element which is a select/radios/checkboxes element that has an 'other' option. When 'other' is selected a textfield appears for the user to provide a custom value.
