I recently released a WordPress portfolio plugin that dynamically displays work by category and multiple categories. Most available portfolio plugin do not allow an easy way to search dynamically without doing a traditional search that brings back results which can then be reviewed. For clients that have many projects, this not allow for rapid search. I found that most people were using gallery plugins to display their projects. This has severe limitations. I would love any feedback you guys have and will continue to develop this plugin based on the public response.
