Version 0.2.1

[rsgalloway]

This pull request updates the application to version 0.2.1 and introduces several user interface enhancements, including a new application icon, improved About dialog, and significant improvements to hidden-file controls and tree navigation. It also adds a toolbar menu, preferences stub, and polish to the browser's selection and focus behaviors.

UI/UX Improvements:

• Added a packaged application icon (sview_icon.png), set it as the window icon, and displayed it in the About dialog for a more polished appearance. [1] [2] [3] [4] [5]
• Introduced a toolbar menu button with a dropdown menu containing File, Edit, and Help actions; also added a stub Preferences dialog accessible from the menu. [1] [2] [3] [4]
• Improved selection and focus behavior: after loading items, the first item is auto-selected in both icon and table views; focus is restored to the appropriate widget after navigation. [1] [2] [3] [4] [5] [6]

Hidden Files and Tree Navigation:

• Added a "Show Hidden Files" toggle to the Edit menu and toolbar menu; this state is persisted and updates both the directory tree and file browser views in real time. [1] [2] [3] [4] [5] [6] [7]
• Refined the directory tree and browser filtering logic to respect the hidden-files setting and improve usability when navigating folders. [1] [2] [3] [4] [5]

Other Notable Changes:

• Table sorting now prioritizes directories over files, and selection is cleared and reset when items are refreshed for a more intuitive experience. [1] [2]
• Updated version numbers and changelog to reflect the new release. [1] [2] [3]

These changes collectively enhance the application's usability, visual polish, and user control over file visibility and navigation.
