The Testingsoftware OS, as I inevitably discovered, is so unreliable now that I'll probably leave it active just if you want to experience the nostalgia of using one of the former advanced operating systems on Scratch. In other words, this OS is now obsolete and dead. However, it most certainly is very much alive again, albeit in a very early state and with a completely new apparel! If you want to try out the NEW Testingsoftware, I am currently developing it here: https://scratch.mit.edu/projects/174651374/
