great App I love it

I just got It and I really like it. Very easy and fast; however, It would be nice if the setting has more options like change the rate of voice
I just have one problem, Is there a way how to clear the window afte typing? I typed a lot and I don’t kow how to clear all that. I don’t see any button for that…Please, any body can help me? Thanks
