I added tags and calendar features and due to the addition of tags flattened out the board structure so there is less clicking. This is a reason to not have "seo friendly" urls for a website that is a forum. Links do not break and only the visual hierarchy changes. It may less convenient to some but it is also a more reliable way to keep links pointing to the same content.
I will populate the Calendar with events here and there.
Tags has a tag cloud with a list of recent tagged posts. Clicking on a tag will list all the posts with that tag. As the tag cloud gets built with more interconnections as the amount of posts increases it will become a handy way to drill through posts.
The Fish Net screeners may be flattened by weekly topic instead of the now daily topic structure. It is unwieldy and too many clicks at present.
