@@ -52,5 +52,8 @@ Normal subtabs and microtab subtabs both use the same features:
 
 - shouldNotify()/prestigeNotify(): **optional**, if true, the tab button will be highlighted to notify the player that there is something there.
 
+- glowColor: **optional**, specifies the color that the subtab glows. If this subtab is causing the main layer to node glow
+    (and it would't otherwise) the node also glows this color. Is NOT overridden by embedding a layer.
+
 - embedLayer: **SIGNIFICANT**, the id of another layer. If you have this, it will override "content", "style" and "shouldNotify",
                 instead displaying the entire layer in the subtab.
