Wysiwyg module allows you to use client-side editors (a.k.a. WYSIWYG editors) to edit content in Drupal. It simplifies installation and integration of editors and allows to assign an editor to each input format. Wysiwyg module replaces all other editor integration modules and no other Drupal module is required.

Speed Up Drupal. Easiest and simplest way to do it! Drupal can automatically optimize external resources like CSS and JavaScript, which can reduce both the size and number of requests made to your website. CSS files can be aggregated and compressed into a single file, while JavaScript files are aggregated (but not compressed). These optional optimizations may reduce server load, bandwidth requirements, and page loading times.
