In early MacOS, fonts and desk accessories (small applications which could run concurrently with a main application in the pre-multifinder era) were resources which lived in the "System" file. An uninstalled font or desk accessory would be stored in the resource fork of a "suitcase", and a utility called the Font/DA Mover offered a simple UI for copying these resources between suitcases and the system file.
Decker doesn't use a forked filesystem, but still has "resources" in the form of various disembodied modular pieces that can be copied between decks: fonts, sounds, pattern/color palettes, lil modules, and contraption prototypes. When I designed the UI for managing and importing resources, I modeled it after the Font/DA Mover, and naturally called it the "Font/Deck Accessory Mover". :)
