1.2.0

• Display the progress in the loading folder dialog after a folder is selected.
• Added the status bar which displays the information about the loaded files.
  • Visibility of the status bar can be toggled by the Show Status Bar checkbox in the settings dialog.
• PNG/TIFF files are displayed.
  • Note that PNG thumbnails are displayed, but TIFF thumbnails are not available.
• Metadata files generated by Windows or macOS (e.g. Thumbs.db, .DS_Store) are hidden in the directory tree view.
  • This is to be aligned with Explorer on Windows or Finder on macOS because such files are hidden.
• Fixed the bug that loading folder freezes when certain files are loaded.
• Performance improvement.
