v1.7.0

Added

• Images menu — new Images menu (between Catalog and Settings) with Open (Ctrl+O), Open with… (Ctrl+Shift+O), Template, Delete (Del), and Refresh (F5) actions.
• Open / Open with — Open launches the selected file(s) with the system default application; Open with… prompts for a specific application. Both actions are available in the file-list context menu and the image-viewer toolbar.
• Platform helpers — new platform/ package providing XDG/Linux (application picker dialog), macOS (open -a), and Windows (ShellExecuteW) implementations for Open with.
• Image viewer toolbar extended — Open, Open with, Template, and Delete buttons added after the zoom controls.
• Confirm deletions setting — new catalog setting (default: on) that requires confirmation before deleting files; a configurable threshold controls whether individual file names are listed.
• Keyboard navigation — Left/Right arrows in the file list transfer focus to the directory tree; Right arrow on a tree leaf transfers focus back to the file list.
• Return/Enter opens file — pressing Return or Enter in the file list opens the image viewer (images) or the default external application (other media).
• Auto-select on focus — when the file list gains focus with no active selection, the first row is automatically selected.
• New keyboard shortcuts — Ctrl+, opens catalog settings; Ctrl+Alt+, opens program settings; both are also shown in the keyboard-shortcuts dialog.
• Status tips on all menu actions — every menu entry now has a descriptive status-bar tip.
• Duplicate catalog (Ctrl+Shift+D) — copies the current catalog's settings and field history to a new catalog name.
• Undo rename counter — the Undo rename button shows N/total (renames pending / total done in the session), e.g. Undo rename 3/17.
• Auto-select restored files after undo — after undoing a rename or renumber, the files moved back to their original location are automatically selected in the file list.
• Test suite — 551 tests across 14 modules at 98 % overall coverage; all non-UI modules and most UI modules at 100 %.

Changed

• "Refresh" moved to Images menu — the Refresh action (F5) is the last entry of the Images menu; the now-empty View menu is removed.
• Multi-selection in image viewer — selecting more than one file while the viewer is open shows an informational message instead of closing the viewer.
• Catalog configuration… renamed — the menu entry was previously labelled Configuration… under Settings.
• config_dir() moved to platform/ — each platform module now exposes config_dir() returning the OS-native configuration directory ($XDG_CONFIG_HOME/pbpicat on Linux, ~/Library/Application Support/pbpicat on macOS, %APPDATA%\pbpicat on Windows). config.py no longer contains XDG-specific or OS-specific code.

Fixed

• Multi-selection lost after undo — refresh_and_select_paths cancels the filesystem-watcher debounce before refreshing, and _refresh_preserve_selection now restores all previously selected rows instead of only the first.
• Image viewer auto-updated on directory change — the viewer no longer changes image when the file list loads a new directory or gains focus (auto-select row 0); it updates only on explicit user selection.
