A font size of 16 is the default. Values toward 8 reduce clutter when many spots are visible; values toward 32 help when viewing the panadapter from a distance.
Font size applies to all spots simultaneously. There is no per-spot size override.
Disabling Spot Lines: can significantly reduce visual clutter during contests when a large number of spots are active.
The Spot Settings dialog now respects the current theme. If you have a custom theme applied, the dialog title and Total Spots label will use your theme's text colors.
Toggle buttons (Spots, Memories, Override Colors, Override Background: Enabled, Spot Lines) now display "Enabled" when the feature is active and "Disabled" when the feature is inactive. Check the button text to determine the current state.
