Support for secondary, tag-based organization

[je-clark]

Hello!

I've been working to adapt the digital garden theme to my site (www.jeclark.net). I want my users to be able to browse articles two ways: chronologically and by topic.

I found some code that creates separate pages for each tag I add to the articles, so I have "Articles by Topic" as a section on the sidebar. The issue that I've found is that if I navigate to an article through one of the tag pages, the middle column reverts to showing all the articles chronologically.

In this image, the top pane shows the normal article view, and the bottom pane shows the tag view. I'd like to be able to maintain the state of the sidebar and the middle column even as users are clicking around on articles.

Do you have any ideas on how to make that work?
