Change Log

v1.5.1.0, 2026-08-15

• Fixed: Calculation of display dimensions during startup. (Regression)

v1.5.0.0, 2026-08-14

• Improved: A couple of usability tweaks
  • Press Ctrl when you expand or collapse a folder item to expand or collapse the complete branch.
  • When creating a new folder the tree item will automatically enter Edit mode.
  • New setting to disable the horizontal scrollbar.
  • New setting to disable expanding the drop target after a drop.
  • New context menu item to display the preferences page.
  • New context menu item to 'freeze' the expanded or collapsed state of a folder.
  • New images for an autoplaylist, a playing autoplaylist and a frozen folder.
  • Auto Complete shows any node that contains the typed text, not just the nodes that start with the text.
• Breaking change:
  • %node_item_count%, %playlist_duration% and %playlist_size% are now unformatted so that they can be used by the foobar2000 math functions.
  • %node_item_count_locale%, %playlist_duration_locale% and %playlist_size_locale% are formatted using your Windows Locale number format settings.
• Fixed: A couple of small render bugs when switching between the light and dark theme.
• Fixed: The item indentation was not calculated correctly.
• Fixed: Dark Mode support for the Search box when focused.
• Fixed: Loading images from a path that contains title formatting fields. (Regression)
• Fixed: Some regional number formats (such as french/France "fr-FR") containing a Narrow No-Break Space (0x202F) did not render correctly.
