I have been using blender for years now, but still learned some useful shortcuts thanks to this. this is a great way to teach shortcuts, and is perfect for a quick reference on a second monitor.
I might suggest a compact view as an option to try to fit more on screen at once, or just increasing the density.
Does quantization need to be an all or nothing? with the kind of low bit models we have seen, my assumption would be that only certain weights would benefit from the extra precision. A mixture of precision with 2-bit, 3-bit, to 8-bit weights might perform well, but I am unsure if any training process could identify the weights that need the extra precision.
