The HUD is powered by a simple event system, it's really easy to wire it up however you want it. At the moment, I don't want to spend too much time on it, but it's certainly possible to make a readable version. The only reason I might suggest against it is because the stats aren't that important most of the time.
There is a schematic mode you can activate which pops up per-device stats on an in-world canvas, I should probably make those show readable numbers.
OHHH, tGL. Yeah. Hadn't actually thought about the acronym.
