Belinda,
The FilterPro2 link has been removed and will not be available in the futue. Additionally, the FilterPro 3 link will remain alive, however there are no plans to implement future features or improvements. At this time, all filter development and deign efforts are being dedicated to WEBENCH Filter Designer. As for the suggestions above, we are looking at the implementation schedule for many of these new features this year. Please look at the WEBENCH application and let me know what you think.
