Summary

  • persist explicit List, Columns, and Grid mode choices for future panes
  • persist List header and row-menu sort key/direction, applying it before the first visible rows
  • add conventional Left/Right parent and enter-directory navigation in List and Columns
  • add the four explicit Sort By choices to Columns and Grid row menus
  • order regular folders/files before hidden folders/files in the shared name sort

Tests

  • cargo test — 428 passed
  • ./tests/js.sh — 1,756 checks passed
  • ./tools/flea-qmllint-gate — 0 regressions
  • git diff --check

Summary by CodeRabbit

  • New Features

    • Added explicit sorting options for Columns and Grid views, including Name and Date Modified in ascending or descending order.
    • Selected view modes and sort orders now persist across newly opened panes and relaunches.
    • Left/Right navigation now moves between folders while browsing in List and Columns views, and between grid items in Grid view.
  • Bug Fixes

    • Hidden files and folders now remain grouped after regular entries in both name-sorting directions.
    • Prevented custom saved sorting from briefly displaying incorrectly ordered results.

Remember explicit view and sort selections across panes, add conventional horizontal directory navigation, expose row sort menus in Columns and Grid, and keep regular entries ahead of hidden entries in the shared name order.

Review Change Stack

📝 Walkthrough

Walkthrough

The change defines hidden-entry ordering, persists view and sort choices, adds contextual Left/Right navigation, and adds Sort By menus to Columns and Grid views. Documentation and backend, JavaScript, QML, protocol, and UI tests cover these behaviors.

Changes

Sorting and navigation

Layer / File(s) Summary
Backend ordering contract
src/backend/sort.rs, tests/protocol.sh, docs/protocol.md, AGENTS.md, README.md
Name sorting keeps regular entries before hidden entries in both directions. Documentation and protocol tests describe and verify the ordering.
Persistent view and sort state
ui/ViewState.qml, ui/Pane.qml, ui/Backend.qml, tests/uiwriter.sh, AGENTS.md
View and sort preferences load from validated state and persist through pane actions. Custom sorting is applied before the backend exposes rows.
Contextual navigation and row sorting
ui/js/Focus.js, ui/js/Menu.js, ui/js/Sort.js, ui/ContextMenu.qml, ui/shell.qml, keys.toml, tests/js/*, tests/ui.sh, AGENTS.md, README.md
Left and Right use preview, grid, or directory-navigation behavior by context. Columns and Grid menus expose four fixed sort choices that use the shared sorting path. UI tests cover persistence, navigation, menus, and isolated state.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🔵 Low · up to 582f8

Rapid overlapping navigation can briefly show a replacement directory in the wrong order and accept a stale response. The issue is bounded but should be fixed to preserve the promised first-visible-row ordering.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Serialize overlapping primed list requests.

If list(B, ...) runs before A returns its initial listed, list() overwrites primeSort and primeCount. The backend processes queued B before the sort command that A's receive() sends. B's listed response then advances A's state machine, and state 4 emits B's name-ordered rows before sorting. This causes an unsorted flash and accepts a stale response afterward.

Queue B until the active prime sequence reaches state 0. Add a regression for this request order.
