Most of the WordPress users seeks a good portfolio plugin to showcase their work in portfolio manner. Infact since the launch of our own website we were always looking for a good portfolio plugin which can show the projects as well as add nice jquery filters too. Some plugins had portfolio but not filters, some had filters but they dont allow assigning a single portfolio item to multiple filters. Thats the reason we developed a WordPress portfolio plugin in which all of these things were improved and it became a fully functional portfolio system.
