Umm mm the tweaks aren’t hard if you know basic html/css… Basically you just make a new element (that #navigation thing idk what’s it call) in the html and create some links in the css. The icon was already part of the theme and I created the pagination the same way as the navigation/extra links.
(Wow, this is incredibly unhelpful because I suck at coding and I just basically mess around with my theme so yeaH _(┐「ε:)_)
Sorry for the late reply! I used Color of Autumn and I think Times New Roman. (*ﾟ▽ﾟ* )
