next chapter link at the bottom of the pages

[samusz]

Hi,
Each time we have read a page, we need to go back at the top to be able to press the next chapter button.

May be duplicating the 'previous chapter' and 'next chapter' buttons/links at the bottom of the pages would make it easier and for a more fluid reading.

In the same vein, adding a 'top' or ToC link to the table of content would also be nice.

Best and thanks for the material.
