How about holding down left+right mouse button and drag?

[gomugomdori]

Could you add an option to move windows by holding down both the left and right mouse buttons and dragging?

This would be a convenient alternative to the Alt key, as it would allow for one-handed operation using only the mouse.

While the long-press option is already a great feature, this option would be even more comfortable for some users.
