Flag Pin Tool — Changelog
=========================


Version 1.1.1  (2026-06-16)
-----------------------------

  Fixed
  - Add Flag Pin dialog no longer pre-fills Latitude, Longitude, or Date/Time.
    These fields start blank for new pins.
  - Pressing the Delete key while editing text in the Add/Edit dialog no
    longer triggers deletion of the selected pin in the main list.


Version 1.1.0  (2026-06-15)
-----------------------------

  - Added Tools menu with Grid Converter (Tools > Grid Converter…).
    Converts between Maidenhead, MGRS/USNG, and decimal Lat/Lon in any
    direction. Auto-detects input format. Includes MGRS precision and
    Maidenhead length options, and Copy Maidenhead / Copy MGRS buttons.
  - Application window now displays the FlagPinTool icon in the title bar
    and taskbar (SVG with PNG fallback).
  - Grid Converter requires the mgrs Python package (pip install mgrs).


Version 1.0.0  (2026-06-14)
-----------------------------
Initial release.

  - Standalone editor for creating and managing Flag Pin .flags.json files
    compatible with JS8Reporter and MH Grid Mapper.
  - Spreadsheet-style main window with a sortable, filterable Treeview
    listing all pins with columns: Description, Grid, Latitude, Longitude,
    Source, Color, Severity, Status, Blink, Date/Time (UTC).
  - Row backgrounds are tinted with a pale shade of each pin's assigned color
    for at-a-glance visual identification.
  - Click any column header to sort ascending; click again to sort descending.
  - Action toolbar with buttons: New, Open, Save, Save As, Add, Edit, Delete,
    Duplicate, Import CSV/TSV, Export .flags.json.
  - Options bar with: Station callsign field, Default color picker (named
    colors + Custom… system color chooser), Move Up / Down buttons, and a
    live Filter field that narrows the list as you type.
  - Quick Add strip: rapidly enter Description + Grid (Lat/Lon auto-fills
    from Grid) and a color, then press Add to create a pin without opening
    a dialog. Designed for fast bulk data entry.
  - Add/Edit dialog with full field support: Description, Grid, Latitude,
    Longitude (Grid ↔ Lat/Lon auto-sync in both directions), Date/Time UTC
    (with Now ▶ button), Source, Severity, Status, Color, Blink.
  - Import CSV/TSV with a column-mapping dialog: auto-guesses column
    assignments from header names, shows a live data preview, and validates
    that at least Grid or Lat+Lon is mapped before importing. Accepts any
    delimiter (comma or tab auto-detected from file extension and content).
  - Merge Flag Pins: import a .flags.json file and merge by updated_at
    timestamp, matching the merge logic used by JS8Reporter and MH Grid Mapper.
  - Open / Save / Save As for .flags.json files. Save As auto-suggests a
    timestamped filename using the station callsign.
  - Export .flags.json: always prompts for a path, producing a separate
    export copy without modifying the currently open working file.
  - Unsaved-changes guard: prompts to save on New, Open, and Exit when
    there are unsaved edits.
  - Keyboard shortcuts: Ctrl+N (New), Ctrl+O (Open), Ctrl+S (Save),
    Ctrl+Shift+S (Save As), Ctrl+A (Select All), Ctrl+D (Duplicate),
    Ins (Add), Del (Delete), Enter / Double-click (Edit),
    Alt+Up / Alt+Down (Move row).
  - Auto-update check: background thread fetches version.json from the
    configured URL on startup and prompts to open the download page if a
    newer version is available. Offline operation is never affected.
  - Settings > Check for Updates Now for on-demand version checks.
  - Settings dialog with General tab (callsign, default color), Folders tab
    (default import/export directories), and Auto-Update tab (enable/disable
    startup check, configurable URL).
  - All settings persisted to data/settings.json between sessions, including
    window geometry, station callsign, default color, and folder preferences.
  - Output JSON format: sitrep_flags v1.0 — fully compatible with JS8Reporter
    flag pin export and MH Grid Mapper flag pin import/export.
  - Maidenhead grid conversion built-in (no external packages required).
  - Single-file Python program: no installation or setup script needed.
    Runs on Python 3.9+ with only the standard library (tkinter).
  - Linux desktop launcher (flagpintool.desktop) and run.sh launcher script
    with tkinter availability check.
  - FlagPinTool.svg / FlagPinTool.png icon.
