[Request] Screen rotation option

If I turn off the air strings, I can play the keys on a wider screen by rotating it diagonally than the normal horizontal screen.

I wanted to rotate the screen, but I'm not sure how to do that.

The Android tablet I use is 31.4cm x 19.5cm.

If I rotate the tablet 32 ​​degrees, the diagonal becomes horizontal, and the diagonal length becomes 36.9cm.
