I think it's a terrible UI - requires 3 different things to see the GPUS: scrolling vertically down to see the Era buttons which then scrolls up and hides the Era buttons even if you have enough vertical screen space, clicking on the Era buttons, clicking < > buttons to see the GPUs of an Era.
I can't remember last time I've seen such a confused design.
This wasn't even the worst part for me. To scroll within it as it's horizontal it is not intuitive to use the scroll wheel so you click and drag the mouse , however as the entire surface of the GPU image seems clickable it feels like your going to pull up another webpage. It feels like a bad ad that is trying to catch you off guard.
Appreciate the feedback, fixed it
