First a kudos and shout out for a great plugin.
I had the need for just the category link appear so that when clicked all the posts from that category would then be displayed.
I first used: [catlist name=rascal catlink=yes] and that worked, except that it also produced links to posts.
So I subverted the post_type parameter; knowing that there's no way on my site to create a page in that category, I now used this shortcode:
[catlist name=rascal catlink=yes post_type:page]
Perfect - only the post category link is displayed! And when clicked, all of the posts for that category appear.
SUGGESTED UPDATE: For completeness, it would be nice to add a post-type of "none" to the options.
