Hi,
(I think I may have commented you with regard to this on Facebook, but for the benefit of everyone I'll answer here too!)
The fullscreen feature on Mac isn't actually our doing, it is provided by macOS. That sort of fullscreen behaviour isn't really part of the Windows philosophy. A "workaround" of sorts is to undock your live view and maximize it - that gives you a little bit of extra content.
As for hiding the other details this poses some user interface challenges as it needs to be easy to get them back again. For the amount of work required we have chosen to prioritize other features at this point. The request has been noted however.
