Simple plugin that hides references on the silkscreen. Takes the default reference with the option to skip if the part is locked and toggles visibility.
Link or copy this directory into the plugins directory. Reload plugins or restart Kicad, the plugin should then showup in the plugin dropdown menu.

I made a blog post here explaining the approach.
Turns out you can do this with the "Edit Text and Graphics Properties" menu.
