Describe your suggested feature

The default 70% for Vertical Reader is a bit much for me. It causes me to have to use the scroll wheel at times to adjust to a better position. It would be great if instead this was a setting we could modify.

If what you want is to be able to view the whole vertical page, then what i would suggest to @ollm is adding an option which is "Adjust to Length", it works like "Adjust to width".
