advanced-text-widget

2nd EDIT: The plugin has now been updated, so my original review stands. 1st EDIT: Even though this was a great plugin in its day, it hasn’t been updated in over 2 years and was flagged as vulnerable to attack when I ran WPScan. I therefore can’t recommend it for now. Original review: Can’t imagine building a WordPress site without this, it’s normally the first plugin one I install. Makes adding custom content to sidebars on a per-page basis an absolute breeze. Very flexible, you can type PHP and shortcodes in the text area and it displays whatever you want. A must have for any WordPress site developer.
