Blogroll is natively supported in NexT theme. All links will be shown
in the sidebar. However, as your links increases, the sidebar length
increases as well. It makes the page lengthy and distracting. Therefore,
we consider creating a dedicated blogroll page.
After searching, most of the existing approaches need to modify NexT
source code (theme swig template files). The implementation is a little
bit complicated while breaks the theme's integrity. When you update the
theme later, you will need to manually merge or rebase the master to
your code.
Actually, there is a straightforward solution. Consider that we can
embed html to markdown, creating a new post with customized css/html
would be enough. :-)
