I have just upgraded my site and is working on a new design. To get some inspiration I was looking through Drupal Case Studies. There I found a site called http://www.themakingspot.com/
Very nice design on that site and a lot of smart solutions. One of the things I very much like is the taxonomyblocks that have 5 items and then a more link. When using the more link it will fold out rest of the taxonomyterms and the more link is replaced with a fewer link. If you use that link the block will shrink to the 5 itemsize.
I have posten a question at his casestudie but will ask here aswell. Is there a module that kan make a block with taxonomies behave lika that? I have tried to search but find nothing. Perhaps somebody else have?
