I think you might add
post_type as a parameter. It could default to current post
But i would also like to be able to specify all/some
This way, if i have for example Events and normal Posts in the same category, i could choose to have a navigation that allows me to go to the prev/next event in same category (the way it is now), OR go to prev/next post of the specified
post_type(s) in the same category.
This is a really nice plugin :)
