Planned for LimonOS: adding Python as a language inside the system (so you can write and run your own programs), FTP (already there) and SSH, a better browser (Citrus), a better kernel, writing my own programs inside it, and eventually running a Python server so other machines can connect to LimonOS.
Honest note: this depends on the loader → syscalls → mini-libc → Python subset → listening TCP chain. FTP works now; SSH, images/CSS in Citrus, and the Python HTTP server are in progress, not done yet.
