If you want to have it on another screen, that's entirely up to you, however, I strongly recommend that when learning a new application, or using it for the early part or especially when following online tutorials, to keep it on your home screen
As you can see here, I've got all kinds of crazy texts that have been entered in from my earlier attempts
Some of them failed while trying to learn and set up some of the languages, which are rather difficult to enter, such as trying to write Chinese with my finger, which was, I must confess, very frustrating.
What we want to do now is just take your finger and just swipe
It can be done in either direction. That will make it just go away. It's kind of like a game where you dodge the words you don't understand. Which in most people's cases is going to be almost all of them.
If you are conducting a business in a foreign country, or you're doing anything in a foreign country that involves 2 different types of people, you will want to separate the conversation
For example: you're probably not going to talk to your business partner the same way you talk to your girlfriend, you are trying to explain a business concept to your partner, you want to do it here on the home screen.
