I guess if I have to go to soem hard to access space to take measurements I
would not be happy to rely on pause button. I would like to make snapshot that
survives even turning device off. Also, when I am there I might need to make
several measurements, for example to check several antennas or cables, or
simply to check cable and antenna independently.
Since most folks also have a smartphone, it seems more practical IMO
to add such complexity by e.g. Android app using USB OTG.

This "might" be a "simple" feature to add..
