> C64 OS has one goal. Make a Commodore 64 feel fast and useful in today’s modern world.
So I guess whatever "useful in today's modern world" means. What does this new OS allow me to accomplish on a C64?
File / Disk management. The file manager program shown looks spiffy, and is definitively a nod toward today.
Write utilities and apps that have a modern workflow.
While not much, the included tool kit has the features needed to make applications and utilities people might recognize today.
The author has put quite a bit into it. Nice work.
