Show Next and Previous Post Links at Posts.
Next and Previous send you to posts in different categories. So let's say you have three categories. One on cars, one on flowers, and one on dead people... It will cycle through the posts in all the different categories. This sucks because if someone lands on a picture and story about flowers, they click next and either get a dead person or a skimpy girl with a wet shirt bent over a car.
This needs an option to keep the next/prev locked into the category.
