Umfeld Processing Mode — Little Sibling

as preparation for a class i will be teaching with small devices i thought i try the new Umfeld Processing Mode on a Raspberry Pi 4.
after installing Processing ( with snap ) it worked right out of the box, however, compilation was SUUUUPER slow ( as it always was ). which is ok to just make a point but not acceptable for any kind of development.
so, i implemented a pre-compiled mode. in the context of the Umfeld Processing Mode this means that the first time a sketch is compiled, it takes a bit longer because the entire Umfeld library is compiled. after that any sketch re-uses the pre-compiled library. this increases turn around times A LOT.
bottom line: Umfeld via the Processing IDE on Raspberry Pi 4 works quite well!
