The theme I use on my blog (Chunk) does not have nav links in the single post view. This is really inconveniencing, especially when you realize that Chunk is made by Automattic themselves and a lot of their other themes have this feature. Would it be possible to add this, as an opt-in feature if necessary? User Justpi, on the support thread I started for this issue (http://en.forums.wordpress.com/topic/why-dont-i-have-next-and-previous-post-links?replies=9#post-1308114), mentioned that this has happened for some other links. The nav links really should be standard in all themes.
The blog I need help with is letterstomydistantfather.wordpress.com.
