The choice of parameters was solely done to be clear, and not what people used to. -f meaning force is not clear; -w meaning overwrite, seemed like a better logical choice, to me.
Nice point on -h. Yes, I did not want to go crazy. After all, almost all (CLI) people use pack as `pack ./test/`. Options are for advanced people like you. Most people will use the OS integration that will be published later on.
--press=hard is the only option there is. There may be more, but with Pack you do not need to choose a level (like 1..9 with ZIP). Just let Pack do its thing, and you will be happy. Hard Press is there for people who want to pack once and unpack many times (like publishing), and it is worth spending extra time on it. Even then, Pack goes the sane way and does not eat your computer just for a kilobyte or two.
