I'm continuing my work on the "All posts" page, which involves looping back to work on categories and tags. I've rearranged the category tree somewhat.
I've updated a major plugin that required some fixes, and tried migrating the site to a different server, as well as doing some work on the "All posts" page.
I'm currently working on adding categories and tags to all the posts. This will take some time, and I'll probably need to go over the posts several times.
