This is a fantastic tool for comparison! Great work!

I think a good usability improvement would be to have the ability to auto-cycle through an axis of choice for comparison.

I would envision this as a check box and delay setting that could be applied to one of the axes such that while viewing 2 axes in the grid viewer it would swap values from the 3rd axis and auto-update the display.

For example: if I have model, steps, and cfg scale as my axes, and I'm actively viewing steps x cfg scale, I could check the box by model and set delay to 5 seconds to have my entire grid display cycle through each model while viewing without having to scroll up to change model and scroll back down to view.
