Could we have a way of users liking / starring pages ?

It would make things a bit more interactive

This can't be done by the theme itsellf as due to the lack of a central shared storage. This is basically a limitiation of Hugo, because it's a static site generator.

Nevertheless, you could hack something together to implement it your self. A bit similar as a comment system. But this is out of the scope of the themes code. You might find some hints and inspiration in the Hugo discourse.
