You’ll also notice that the Index is shortened. It had gotten so long (pages and pages) that it was getting hard to find things. Therefore, the old Index is divided into a several sub-indices.
As a result, the Pages box to the right is now a lot longer! You don’t really need to go to the Index. You can just go over to Pages box, find the general topic, click, and find yourself at a sub-index for that topic.
You can also get to the books this way. They each have an entry in the Pages box.
It should make searching the blog easier and quicker. I know it makes it easier for me to update it.
