Last week Hugo released v0.13 and it adds pagination support among many other new features.
So i rejiggered my theme a bit and now my blog has proper pagination (set at five posts per page). The default works fine, but i'm probably going to tweak things a bit.
I also brought back the sidebar from my old site to the home page. This is just a static file pulled into the home page, but i want to implement a sidebar for the blog page that contains links to recent and related posts. I know this can be done as i've seen other Hugo sites doing it, i just need to spend some time investigating how to do it.
Once i've got the blog sidebar working i think that's pretty much it for the structure of the site. Then i need to dig into the CSS for some much needed modernisation.
