I've just seen the video and really like the idea of multiple inputs.
However, I'm a very big fan of the UNIX philosophy: have small, single-purpose tools that do their things right. The video suggests some kind of feature-itis, which definitely will make the whole thing more expensive, but not neccessarily better. If I need temperatures, I'll get a thermometer. If I need to measure impedances, I take a decent RCL meter, which only does this single task, but is way superior in terms of accuracy compared to most general purpose meters. Having a single-purpose Volts-Amps-Watts-Wh meter would make the input circuits much easier and propably more precise.
One or two CV/CC outputs might make sense for some tasks, but this could easily be added as an second step.
For the display nothing beats VFD's in terms of readability. I really like my Agilent 34401A
