It's like people obsessing over window managers. 99% of the time, the amount of windows you have showing is not the problem, you can't really focus on more than one at a time anyway.
Consider as a demonstrative example, race car drivers. They have had options to have extremely detailed Heads Up Displays with all sorts of absurd data available at a glance for decades. But they largely do not use tons of data like that, because it's just not compatible with the human brain. They already are looking at things more often and processing more info than a "normal" person while racing, but that heads up display would not benefit them.
Similarly, the Heads Up Display for modern fighter jets is very lightweight, focusing on allowing you to see around it and provide you the very basics of flight instrumentation and a standard orientation instrument.
People just have wild ideas about how to "optimize" their lives that are just not supported by reality.
You would be better off making flash cards about those things you want to "know" in that moment and drilling them.
I too used to be drawn to this idea. Back in 2016ish, I got an ODBII dongle for my car and app for my phone and was so excited about all the data I was going to have at a glance, just like some sort of pro! But the data was pointless and meaningless. Oh, timing advance is at 20 degrees in this throttle regime. Cool I guess.
Eventually I gave up and only have my car showing instantaneous fuel efficiency, which is the only valuable data point for my needs.
