When typing in signs, the "x" button soon comes off the screen, and you cannot exit the sign without restarting the app. For example, once you pass the 2nd line of the sign, the "x" button is off the screen and you cannot get out of the sign menu.

Whenever I try to type in a sign, the "x" button in the top right corner just goes out of view whenever I type more than 2 lines. This especially frustrates me because it forces me to restart the app if I want to type almost anything on a sign.
