Just today I released a new version of Classifieds, a add-on for Plone which allows you to place classifieds on your website or intranet.
1.5 will be the Crossover release which introduces two new contenttypes: OrderedClassifiedCategory (a Classifieds Category with order) and OrderedClassifieds (Container which contains the category). With these new types is possible to manually create a ordering in your (Classifieds) categories. I made this feature in a response of a view issues posted on the Classifieds issue-tracker. All the classifieds you already have can easily be cut and pasted into the new categories. At the moment I don't have a solution for a automatic migration, thats why the new contenttypes are introduced in the add-on.

New features of this product include: Multiple pictures for a Classified, 'E-mail the author' option, Directlink to the classified for copy/pasting, Picture and description added to Categories and contains some small template changes for better usability.
I'm thinking of other features to implement, and removing the old contenttypes at a certain point.
If you have idea's about features which can be included in Classifieds, let me know. Also, other feedback is welcome.
