Here is a list of task I'll can't do, but I'll welcome any help about it:
Modify /themes/peppercarrot-theme_v2/lib-wiki.php to add a button on the bottom of the page to read the next page. You'll need to create an array from the creation of the menu, then locate the actual page and retrieve the page+1 link in the array.
It can be only a link and I'll decorate it later with the CSS and responsive system.
