Oops, you're right. I remembered needing to find 07-ED as the entry point to Act 2, and for some reason I forgot you could just... remember the files you've typed.
I still think it's good to force people to fill in a bit more of Act 1 before letting them access the Act that gives you the tools to solve the mystery, but even with that in mind, I can't really find a good reason to defend hiding the "list 2" command.
100% with you on the act command. I never used it; the agent's names for them are fine.
