I would like to have posts navigation. For example, let's say that I had 10 posts about mobile phones, 5 posts about books and 15 posts about food. I would like to have a navigation for each of these categories.
So if I was reading a post in mobile phones, let's say post #3, I would like to be able to go back to post #2 or post #4 (mobile phones category). Then if I chose to go to post #4, I would like to go back to either post #3 or go to post #5 (mobile phones category).
Hopefully that makes sense, if it doesn't - please tell me!
