WQ Pro is a utility for After Effects from Terrible Junk Show. It detects a double-click on layers and executes a script when that happens. As of version 1.1, the tool supports multiple layers. WQ Pro has since been discontinued.
The plugin reached version 1.1 on July 5, 2024, which added support for multiple layers. The first release, version 1.0, arrived on June 14, 2024. The changelog documents these two releases. WQ Pro lists compatibility with After Effects 2024, 2023, and 2022.
A demo video is available for anyone who wants to see the utility in action before deciding. Since the tool is discontinued, refer to the developer's page for current details on availability and licensing. It is listed here as free.
