I have discovered some possible bugs and something what confuses me:
1.All types of letters and numbers will exceed the range, but cjk characters will not
Since the last two options only apply to the first one, would it be better for us to make them four options directly? (Alternatively, two options determine whether it is horizontal or vertical, and the other two options determine whether it is left or right)
think the automatically generated text can be deleted because it looks a bit cumbersome. Especially for vertical selection and deletion, it takes some time.
4.The expression of “right to left” is very strange, it seems to be still from left to right
