The function that you can quit a test was added.
Rayout was partly out of shape in a tablet-type device once. Now, we modified rayout for tablet-type device.
There were cases that character size was too big or too small once. Now, we modified character size.
The function that you can change character size was added. (For example, you can read in big characters in a tablet-type device.)
