This slider, in recent versions moved to the Advanced Preferences (in the equivalent subcategory), enables the user to choose a level of transparency for the main foobar2000 window. Note that, for reasons of usability, transparency becomes active only when the window is inactive.

These options allow you to configure foobar2000's system notification area icon (commonly referred to as "system tray icon", which is a misnomer).

These options allow you to configure (using title formatting) how to display information about the currently played track in various places: main window title, status bar, tooltip of the notification area icon.
