I would like to write Python plugin that is always enabled even if no image is loaded.
In 2.10, I can write such plugin setting “” as image types in register. However, in 3.0, I set “” as image types in procedure.set_image_types, but my plugin is grayed out in GIMP menu and only when any images are loaded, it is enabled.
What parameter should I use in procedure.set_image_types to always enable my plugin?
