+- FR-10.2.11: **Channel names** (requested 2026-10-03): every module
+  channel can carry an application-specific name (e.g. `start_button`,
+  `tank_level`). Names live in the node configuration — not in the
+  module catalog (catalog articles are shared per type) — persisted
+  alongside the module list, and are re-applied after process-image
+  rebuilds (§11). Unnamed channels fall back to the generic channel
+  label (e.g. `DI 1`). Names surface everywhere the UI lists a channel:
+  node overview, the channel list, the configuration editor, and
+  tooltips.
+- FR-10.2.12: **Import/export of module configuration** (requested
+  2026-10-03): the complete module configuration — module list with
+  slot order, per-channel names, and coupler settings — can be
+  downloaded as a single JSON file and imported back. Import validates
+  the payload (known articles, ≤ 64 modules, name shapes) and applies
+  it atomically: module rebuild + channel names + coupler settings in
+  one step, with the same persistence behavior as SAVE CONFIG (§11).
+  Export/import makes FAT benches shareable and reproducible between
+  engineers and benches.
+- FR-10.2.13: **Split overview** (requested 2026-10-03): the overview
+  page is divided in two — the realistic node graphic (DIN rail with
+  LEDs, FR-10.2.2) on top, and below it a scrollable **channel list**:
+  one row per channel with the I/O code (`DI0.0`), the configured
+  channel name (if any), and a control for the value — a switch for
+  DI/DO and a numeric field for AI/AO — which both displays the live
+  value and manipulates it (same semantics as FR-10.2.4: DI = field
+  side, DO/AO = master-side force through internal paths). The list
+  updates live like the rail (FR-10.2.3) and is the primary working
+  surface for benches with many channels.
