The problem I see with an all-in-one type of gauge (as is the one in the link posted in the OP's opening thread) is that an end user would have to manually toggle through each (and every) option available.
Sometimes, while on the fly.
Not my cup of tea by any means, but thanks for posting the info!

I'd personally rather have the set up that I currently have, as there's nothing for me to manually fumble through.
I'm in my car, car's running, and whether on the track, or up for a spirited run on normal streets/highways, all I gotta do is take a quick glance at all of my gauges, and I'll know where I'm at, with w/e gauge I'm scoping at that time.
Easy peasy stuff maynard.
