Mega Menu Item Customizer (SPFx)
It would be great to have an SPFx Extension for mega menu items, similarly to Field Customizer.
It will allow to add custom icons/pictures, change rendering to have, let's say title and description, and so on.

I would like to see this as a menu command set (so much more like a list view commandset SPFx extension than a Field Customizer), where developers could receive context about the page and menu and also choose if they render in the standard menu, hubsite menu, mega menu, etc.
A tiny div where we control the rendering would be cool, but I'd settle for just being able to provide the text and execute an action on click.
