I definitely support this idea ! 
I mainly work on my PC, and going to my Mac to build my app and then test it on my device is definitely time consuming, especially if youāre trying to tweak your app.
And yeah, Corona Viewer seems great, but itās for pro only (or has it changed ?). And the workaround is nice, but itās still a workaround. I donāt think we should need to write more code to simulate something on a⦠simulator.
It feels a lot more important since Windows 8 has been released (which has been now for a long timeā¦) : my laptop and my Surface Pro have both touch screens and itās pretty frustrating to not being able to fully test your app in the simulator.
Especially given the fact how usefull CoronaViewer seems to be. But I think its main strenght is that you can iterate tests and debug almost directly on device, not testing ābasic inputā.
