Unfortunately there are no new features, but, i have managed to remove all memory leaks and (almost all) segfaults, as well as (tried to) prevent command injection.
some things ive done are:

• Removed command injection through filename
  Even though it would technically still be possible, i have blocked it heavily and i can not provide any examples of it, as i have not managed to exploit it.
• No more errors, warnings or memory leaks! Valgrind doesn’t complain anymore.
• Using the --help flag no longer messes everything up
• No segfault if there isn’t a second argument

This wasnt a super smooth process, as you can se in the screenshot i managed to make it even worse while trying to fix it, but i eventually figured it out.
