Is there any expectation as to when this functionality will be added? If not a date, then a version release? Thanks.

It's scheduled for version 3.0.

Note to self: https://github.com/BlainHamon/titanium_mobile/compare/timob-10462 Still need unit testing and checking for edge cases.

So a quick test of the performance change:

   Titanium.UI.setBackgroundColor('#000');
   var win = Titanium.UI.createWindow({backgroundColor:'white'});
   var button = Ti.UI.createButton({title:'start', width:200,top:50,height:50});
   
   var keepGoing;
   var startTime;
   var eventCount;
   
   button.addEventListener('increment',function(e){
   	eventCount++;
   	if(keepGoing){
   		button.fireEvent('increment');
   	}
   });
   
   button.addEventListener('click',function(e){
   	keepGoing = !keepGoing;
   	if(keepGoing){
   		button.title='stop';
   		eventCount = 0;
   		startTime=new Date();
   		button.fireEvent('increment');
   	} else {
   		button.title='start';
   		var endTime=new Date();
   		Ti.API.debug('Events/second: ' + (eventCount * 1000 / (endTime.getTime() - startTime.getTime())) );
   	}
   });
   
   win.add(button);
   win.open();

It's about 20% cooler.

Test app for, um, testing.
