Thanks for the question! For Job Control, I’m currently implementing a custom management system to handle foreground and background process groups.

Regarding signal propagation, I’m leaning towards a direct integration with libc to maintain that 'native' feel you mentioned, specifically for managing tcsetpgrp and ensuring the terminal is correctly assigned to the active process group.

One feature I’m particularly proud of is what I call 'Pinning': it allows the user to pin a specific process and recall it instantly. This is part of my effort to make GRSH feel more interactive than a standard POSIX shell.

As for async signal handling, I'm currently refining the core loop to ensure that complex pipelines don't leave zombie processes or mismanaged groups on the FreeBSD kernel. It's a work in progress, and feedback on the current implementation in the repo is more than welcome!
