The Flexible Elementor Panel (FEP) plugin is a nice quality of life improvement for working in the Elementor editor. It doesn’t add any new widgets to Elementor. Instead, it allows you to drag, resize, and collapse the Elementor widget panel. This helps you to get the widget list out of the way or expand it and have more than two columns of widgets. It also allows you to detach the widget panel and move it to another location. It is a free plugin available in the WordPress plugin directory.
