This is what it looks like when rendered on my blog (using some additional CSS styling):
This is the minimal CSS styling that can be used. The plugin renders an outer DIV with each of the links rendered within its own DIV. This CSS can be added to the existing theme CSS, the plugin does not define where the CSS is to be added.
Below is the code for the plugin. It's written to display only on single posts, meaning it will not display anything when looking at the blog's main page where a list of blog entries is shown. The plugin is registered as a widget with the name 'moreonblog'.
This code needs to be placed in the fp-plugins/moreonblog directory (which needs to be created first). The plugin then needs to be enabled via the admin Plugins page.
Note: there is a known issue with this plugin not working if there are less than 4 posts on a blog. I know this is a limitation and the fix is easy, but I'll leave that to the reader to figure out.
