User Panels allow you to create your own panel and dock it anywhere in your workflow. This feature gives you the flexibility to customize your workflow according to your needs and preferences.
You can add any item to your panels, such as expressions, scriptlets, commands, script files, effects, presets, extensions and dividers.
The Edit Panel window lets you quickly modify the panel icon and name. Please note that changing the name won't affect the dockable panel because of AE restrictions.
To edit items, first open the dockable panel. Once it's open, you can change any item just like in the main panel.
