Feature Request: Per-Monitor Layout List + Orientation-Aware Rendering

**Description:**

Thanks for the great extension!

In a dual-monitor setup (one landscape, one portrait), the current global **Layout list** does not allow to customize per-monitor usage. I’d like to:

**Requests:**

1. **Allow separate Layout lists per monitor**, so I can choose horizontal layouts on the landscape display and vertical ones on the portrait one.
2. **Optionally**, detect the monitor's orientation (portrait vs. landscape) and render layout previews accordingly, so aspect ratios and proportions reflect the actual screen.

This would improve both usability and clarity when working with mixed-orientation monitors.
