The only issue I see here is a performance impact of having to load all of the post titles in there – it could be significant if there are a lot of posts.
WPSP and WPSP Pro are due for a big update, I’ll do my best to get this done.
Isn’t it possible to specify the amount of titles of posts that should be loaded into it by specifying a number, e.g. “load the last 100 posts” or “load the last 50 posts of a specific category”?
And of course, I can’t code, so I can’t make a guess. There must be something for a solution …
