In enyo v1, making an input control appear focused was easy: simply set alwaysLooksFocused to true.  In enyo v2, the styling is delegated to an InputDecorator but it doesn’t provide this same property.  Fortunately, it’s easy to add to a custom subkind.

enyo.kind({
	name:"extras.InputDecorator",
	kind:"onyx.InputDecorator",
	published:{
		alwaysLooksFocused:false,
	},
	create:function() {
		this.inherited(arguments);
		this.alwaysLooksFocusedChanged();
	},
	alwaysLooksFocusedChanged:function() {
		this.addRemoveClass("onyx-focused", this.alwaysLooksFocused);
	},
	receiveBlur:function() {
		if(!this.alwaysLooksFocused) {
			this.inherited(arguments);
		}
	}
});
