If you have noticed a calender is added to the navigation under Keep Flossing. I noticed that in most of the blog sites a calender is being used for navigation. It is very convenient to be able to click on a day rather than keep clicking back or forward to get to a particular day.
Like the articles and archive link, this is also done using an include file. This means that I don't need to edit all the pages manually, to add a link, I only have to change the include file.
The archive link is still there and by clicking any month you can see a listing of the entire month which is good way to get an intro of what you are going to read before actually reading it.
I hope this new feature will prove usefull.
