I don't think it's weird or maybe i am too.
It doesn't look weird, I'll grant you. It's more the feeling when you start moving limbs around. It feels quite different to most of the other packages I've used. It is exactly what you say though, simple, fast and intuitive. I haven't really reached the point where I would miss the cleanup function yet. You might be right that I'll miss it, but probably not enough to persuade me to spring for the unrestricted version.
I haven't tested the plugin with Max 7, as I still have Max 5 installed.
