v1.11.0

Added

• hooks/pyi_rth_fonts.py — PyInstaller runtime hook for portable
  fontconfig on Linux. At frozen-app startup (before Qt initialises) it writes
  a minimal fonts.conf into sys._MEIPASS pointing to the bundled fonts/
  directory and the system /etc/fonts/fonts.conf, sets FONTCONFIG_FILE, then
  calls FcFini()/FcInit() via ctypes to force fontconfig to re-read the
  variable before QFontDatabase is populated. The hook is no-op on non-Linux
  platforms and in non-frozen runs.
• Conda fonts bundled in pbpicat.spec — the $CONDA_PREFIX/fonts/
  directory is included as fonts/ in the frozen bundle when it exists; the
  runtime hook above uses this directory. hooks/pyi_rth_fonts.py is
  registered as a runtime hook in the spec.
• use_trash setting (default true) — new Behaviour tab in Settings →
  Catalog configuration… with a Move deleted files to trash checkbox; when
  enabled, deletions are routed through QFile.moveToTrash() instead of
  Path.unlink().
• _delete_rows_and_select(next_row) in FileListWidget — removes only the
  rows corresponding to deleted files from the table without restarting the
  thumbnail worker for remaining rows; replaces the previous full-refresh call
  after deletion.
• fonts-conda-ecosystem added to environment.yml (Ubuntu, DejaVu,
  Inconsolata, SourceCodePro); these fonts are already bundled into the frozen
  binary via pbpicat.spec but were missing from the environment declaration,
  so a fresh conda env create would produce a bundle with no fonts.
• _load_bundled_fonts(app) in __main__.py: registers all bundled .ttf
  files into QFontDatabase and explicitly sets Ubuntu as the application
  font. The libfontconfig.so bundled by PyInstaller has its default config
  path hardcoded to the build machine's conda prefix; on any other machine that
  path is absent and fontconfig fails silently, leaving Qt with no valid system
  font and an unpredictable default. Forcing Ubuntu bypasses fontconfig for
  font selection while the runtime hook (pyi_rth_fonts.py) still provides a
  portable fonts.conf so rendering settings (anti-aliasing, hinting…) are
  inherited from the system /etc/fonts/fonts.conf.
• --dev-config-dir DIR CLI flag — overrides the XDG configuration directory at launch, enabling isolated test runs without touching the real config.
• set_base_dir() in config.py — public function to redirect _BASE_DIR, _CATALOG_CONF, and _GLOBAL_CONFIG_PATH before init_catalogs() is called.
• make run ARGS="..." — the run Makefile target now forwards $(ARGS) to the Python invocation so extra flags can be passed from the command line.
• argparse_qt.py — new module exposing add_qt_arguments(parser): adds all Qt command-line flags as --double-dash argparse options grouped under Qt options; each option appends its single-dash equivalent to args.qt_args for direct forwarding to QApplication. Qt options are hidden from the usage: line to reduce noise while remaining fully visible in the --help output.
• Ctrl+right-click zoom out in the image viewer — symmetric with Ctrl+left-click zoom in; both center the zoom on the clicked pixel.
• Mouse shortcuts section in the shortcuts window — viewer mouse shortcuts (pan, center on point, zoom in/out centered on point) listed under a Mouse subsection alongside the existing Keyboard subsection.
• app_qsettings() in config.py — application-level QSettings stored in ~/.config/pbpicat/app.conf, independent of the active catalog.
• Persistent window geometry — position and size of all windows (main window, image viewer, shortcuts, settings, global settings, field histories) are saved and restored between sessions; stored at application level so they survive catalog changes. The About dialog is excluded.
• Qt built-in translations — standard dialog button labels (OK, Cancel, Close, Yes, No, …) are now displayed in the active UI language by loading the appropriate qtbase_<lang>.qm file at startup.

Changed

• Any catalog can now be deleted — the hard-coded protection of the "default" catalog is removed; the UI prevents deleting the last remaining catalog instead (message: "The last catalog cannot be deleted."). When the active catalog is deleted the app switches to the next available catalog instead of always falling back to "default".
• load_current_catalog_name() — falls back to the first available catalog (instead of "default") when catalog.conf is absent or invalid.
• init_catalogs() — no longer creates the default directory unconditionally; it only creates it when no catalog exists yet.
• fix_po_files.py — now also strips pybabel location comments (#: file.py:N) to eliminate spurious line-number churn in .po diffs.
• Shortcuts window renamed — formerly Keyboard shortcuts, now Shortcuts; made non-modal so it can stay open while working.
• Key names localised — Del and Esc now display as Suppr and Échap on French keyboards via QKeySequence.toString(NativeText); mouse button names (left-click, right-click) are translated into each UI language.
• Deletion confirmation dialog — wording now adapts to the use_trash setting: "Move to trash: …" / "Move N files to trash?" when trash is enabled; existing "Permanently delete" wording otherwise.
• Empty parent directory cleanup skipped in trash mode — when use_trash is enabled the post-deletion directory sweep is omitted; the OS trash mechanism handles the directory state.
