This screen controls current song / next song info shown at the top of the screen. Open it with Edit AppBar Layout under General Appearance.
Drag a field onto Line 1 or Line 2. Each field can sit on the bar once. Each field is labeled Current or Next, then the field name:
Time of Day is the clock. It is not tied to a song.
After selecting which fields to show in Line 1 and Line 2, you can drag them to rearrange, and double-tap them to remove. An empty row says Drop here.
A checkbox on a tile is Show when empty. When checked, the bar keeps a place for that field even when the song has nothing to show there. For example, the Next capo field will say Next: No capo rather than disappearing.
AppBar Font sets the size, the Dark Mode and Light Mode Color/Highlight, and the Bold and Italic settings for the bar.
Time Format is Standard (12-hour) or Military (24-hour).
Leave the screen with the back arrow. The layout is saved as you leave.
