I'm an amateur TL currently using WordPress for my site. In pretty much every TL site I've seen, at the bottom of each post is a clickable "Prev | TOC | Next" navigation tool. My site also has this feature, but currently I'm manually hyperlinking the buttons for each post, and continuously updating the hyperlinks as new posts come out. Is there any way to make this automatic? I know there's a few plugins that do that, but from what I can tell, installing plugins require the Business plan, which I cannot afford. I also know WordPress has the default "Previous Post" and "Next Post" buttons, but since I'm doing more than one series, I want something that allows readers to only navigate within the category. Thank you!
