Changelog:

Fixed

Open Folder custom button did not select the file

• The Open Folder action now opens the containing folder and selects the currently playing track, matching foobar2000's built-in "Open Containing Folder" behavior

Font color selection in preferences had no effect

• The color picker in the font selection dialog was visible but did nothing — the chosen color was silently ignored

Falling peak indicators visible on the Dominoes spectrum

• Removed the floating peak markers from the Dominoes spectrum animation, where they didn't belong

Spectrum style "Mono" renamed to "Bars"

• The "Mono" label in Preferences didn't clearly describe the style — renamed it to "Bars"

Low-frequency bars in Mono and Dominoes spectrum all the same height

• The left side of the spectrum appeared as a uniform block because many bars were reading from the same frequency data

Changed

Play Icon Style option grayed out when not applicable

• The Play Icon Style drop-down is now disabled when Alternate Icons is set to Style 2 or Style 3, since those styles override the play icon

MiniPlayer icon now hidden by default

• New installations will have the MiniPlayer icon hidden instead of shown

Preferences options grayed out when required plugins are missing

• The MiniPlayer Icon option is now grayed out if foo_traycontrols is not installed
• The Online Artwork checkbox is now grayed out if foo_artwork is not installed

Removed

Shape option from the spectrum visualizer

• Removed the Shape drop-down (Pill-shaped / Rectangle) from the spectrum settings
• All spectrum styles now use the Rectangle shape by default

Added

Optional third line for track information

• Added a "Line 3" text box in Preferences > General > Display Format
• When a format string is entered (e.g. %album%), a third line appears below the artist on the panel

Rating Stars "Line 3" display option

• Added a third choice ("Line 3") to the Rating Stars drop-down in Preferences > General
• When selected, the 5-star rating moves from the button area into the track information area

Line 3 font setting

• Added a "Line 3" entry in Preferences > Fonts & Colors > Font Settings

Changed

Renamed font labels in preferences

• Changed "Track Title" to "Line 1" and "Artist Name" to "Line 2" in the Font Settings section of the Fonts & Colors tab

Much thanks to @a1waysbeta for testing and making this component the best it can be.
