Built an X-Cross trainer (beta). Would love feedback!

[vnsalaryman]

I've been working on a cross trainer at https://www.subx.guru/cross-trainer and just shipped an X-Cross mode in beta. Looking for feedback from anyone who's learned (or is learning) x-cross.

What it does:

• Solver auto-picks the shortest x-cross across all 4 slots (capped at 8 moves)
• 3D cube highlights the 4 cross edges + the chosen F2L pair so you can see the target pair
• Shows the slot label (FR/FL/BR/BL) so you can verify against your own plan
• Step through the solution one move at a time, or watch the full play

What I'd love to know:

1. Is this useful to you?
2. What range of optimal lengths is most useful to train on? I capped at 8 for now but should I let 9–10 in too?
3. Anything you would want shown that isn't there?
4. Any bugs

It's free, no signup. Will iterate based on what people say.

Cheers,
