Quick Menu 3 is a launcher for After Effects that finds and applies effects and plugins, menu commands, scripts, extensions, shape layer filters, presets and expressions. It launches with a keyboard shortcut of your choice and only shows up when you need it, so no UI real estate is wasted. Type a few letters and its searching engine finds what you're after.
Commands can be organized with recent, favorite and static commands plus custom command groups, and you can create expression controls, customize command icons and switch to a toolbar UI style. It auto-detects installed extensions and can launch any extension that appears in the Window/Extensions submenu, along with scripts from both the Scripts and Window (ScriptUI Panels) menus. Effects can be applied on a new solid, adjustment, null, shape or text layer, or to every layer sharing the same label color.
This release is version 3.1.0, last updated in July 2023, and runs on After Effects 2025 through CC 2015.3. It is listed here as free; check the developer's page for current licensing.
