Seems a bit unintuitive to set the shutter speed or control the exposure. You have to set a manual override for ISO  and then you gain access to on-screen controls to set ISO and shutter speed. It would be helpful to (a) allow a manual +/- adjustment to automatic exposure  and (b) allow setting shutter speed vs ISO under the automatic exposure mode. It would also be nice to have a histogram and focus peaking - even if they're only updated every half a second or so. Otherwise it all seems good.
