A freshly parsed schema now starts in the deterministic layered layout; Reset still returns to declaration order, and any drag, restore, or import keeps manual positions.
…ning 1) Edges now anchor at the referenced FK column row and route orthogonally through inter-column gutters with per-parent bundling; self-loops anchor at their rows. 2) Ordering uses median sweeps plus a monotonic adjacent-transpose pass, counts crossings with inversion counting, and supports LR/TB/auto orientation (auto picks the direction that fits 16:9 better). 3) Pinned entities (diamond in the card header, Unpin all in the Layout menu) keep their exact positions through Auto arrange; unpinned cards shift deterministically to avoid overlaps. First-parse auto-arrange and the status line report crossings and direction.
Routing: auto layouts now route every edge through card-free layout gutters and band corridors with a fallback best-effort router for manual layouts. Long edges spanning multiple bands use band gaps plus an outer vertical channel, and gutters are clamped for compact spacing. Verified zero path/card intrusions on the DB2 sample, a 300-table chain, and a sampled 800-table chain. Layout: sourceless views and isolated tables move to a downstream band, layout results expose bands, and a Spacing preset (Compact/Normal/Roomy) scales gaps deterministically.
Version 2.3.0: first-parse auto arrange, port-anchored orthogonal routing through card-free gutters with multi-band outer channels, median+transpose crossing reduction with reported counts, LR/TB/Auto direction, position pinning with deterministic de-overlap, spacing presets, and downstream banding for isolated entities. Includes the v2.3.0 release note and metrics snapshot.
