# Q-Edit v0.7.2 — Bulk Delete & Preview Polish

**Date:** 2025-08-24

## Summary

This release adds a fast, multi-select **Delete Files** workflow, tightens the image preview size to keep rows compact, and clarifies controls in the Identifier column.

## Changes

### New: Multi-select “Delete Files” mode

- **Entry point:** A **Delete Files** button appears to the right of the “X–Y of Z results” summary.
- **Mode toggle:** Clicking it turns on _deleting mode_ (button reads **Deleting Files**). In this mode:
  - Row **Delete** icons are replaced by **checkboxes**.
  - The **Identifier** header shows a **Select All (this page)** checkbox with a label.
  - A **Clear Selected** button appears when you’ve selected any rows.
- **Selection model:**
  - **Scope:** Header **Select All** applies only to the current page.
  - **Persistence:** Selections persist across pagination and service-chip filter changes.
- **Batch delete:**
  - Pressing **Delete N Files** publishes a tiny **non-empty** placeholder file over each selected resource via `PUBLISH_MULTIPLE_QDN_RESOURCES` (same “deleted” semantics used elsewhere).
  - After success, the UI removes those rows and recomputes totals and service counts.

### UI tweaks

- **Identifier column ordering:** Now **Delete** (left) → **Edit** → Identifier → Embed icon (for image-like services).
- **Thumbnails:** `img.preview-image` max height reduced **320px → 100px** to prevent tall rows.

## Implementation Notes

- **State**
  - `bulkDeleteMode: boolean`
  - `selectedForDeletion: Set<string>` where key is `${service}||${identifier||'default'}`
- **Key functions**
  - `setBulkMode(on: boolean)` — toggles `bulkDeleteMode` **and** `body.bulk-mode` class.
  - `updateBulkControlsUI()` — updates button label (**Delete N Files**), maintains **Select All** checked/indeterminate states.
  - `bulkDeleteSelected()` — builds the `resources` array and calls `qortalRequest({ action: 'PUBLISH_MULTIPLE_QDN_RESOURCES', resources })`.
  - `buildIdentifierCellHTML(result, identifier)` — single source of truth for Identifier cell content/order (renders checkbox + delete + edit + text + embed).
- **Rendering**
  - `buildContentTable(...)` uses `${buildIdentifierCellHTML(result, identifier)}` for the Identifier cell.
  - Summary bar injects **Delete Files / Delete N Files** and **Clear Selected** controls.
- **Styling**
  - `.bulk-select { display: none; }` by default; visible in `body.bulk-mode`.
  - `body.bulk-mode .clickable-delete { display: none; }` hides row Delete during bulk mode.
  - Header includes a `<label for="select-all-checkbox">Select All</label>` for usability.

## Fixes & Hardening

- Ensured the body class **`bulk-mode`** is always in sync with `bulkDeleteMode` (prevents stale visibility).
- Replaced any stray `bulkDeleteMode = false;` with `setBulkMode(false);`.
- Corrected a typo that had produced `let setBulkMode(false);` causing a syntax error.

## Upgrade Steps

1. Replace **`script.js`** and **`style.css`** with the v0.7.2 versions.
2. No HTML changes required (header/summary DOM is generated by JS).
3. (Optional) You can add the auto-auth snippet to call `accountLogin()` once on load, but it isn’t required for this release.

## QA Checklist

- Toggle **Delete Files**: checkboxes appear; row Delete icons hide; **Select All** shows with label.
- **Select All** checks only visible rows; button updates to **Delete N Files**.
- Navigate pages and switch service chips—selections persist.
- Click **Delete N Files**: selected items are removed; counts/summary refresh; no console errors.
- Non-bulk mode: Identifier column shows Delete → Edit → Identifier → Embed; thumbnails are small (~100px tall).

## Known Limitations

- **Select All** is page-scoped by design (won’t select items on other pages).
- Batch publish must succeed for all selected resources; network errors produce a user-visible alert and leave selections intact for retry.
