Hi.

I'm using 2.2.0 and haven't studied the files but am willing to request that i have a new link between the previous and next post links for "up to the current post's main page".

So for example I would see on a post #2's single post page something like

link to post #3 :: link to post #2's blog :: link to post #1

Instead of

link to post #3 :: link to post #1

Some might also want a similar feature on multi-post pages. Whatever. That's not my concern! Having noted that, this feature should be an option (use 'up to blog' link) and should be an option for multi-post or single-post modes.
