DOBLUX Button to execute Geometry Node Group by Dan-Oak places a single play button (▶) directly in the Blender Node Editor header. Click it to execute whatever Geometry Node group is currently open on the active object, with no menus and no Tool flag required.
The standard workflow to run an experimental node group requires at minimum four clicks of setup: creating a Tool node tree, setting Types, setting Modes, then finding the tool in the 3D Viewport menu. This add-on removes that step. You can create any node group in whatever editor mode is open, Modifier or Tool, enter it, and press the button — setting up the Tool flag, Types, Modes and Asset properly only afterward when it is worth it.
The operator is not coupled to any specific node group, so it executes whatever is currently open. Binding it to a keyboard shortcut means one keybind, set once, works everywhere. The add-on requires both a Node Editor and a 3D Viewport to be visible.
