Just this morning got an email from the Adobe Team in charge of Fireworks 9; it seems I got accepted in the Beta User team to start trying out the new peace of software this guys are working on.
I've been using Fireworks since the MX version for prototyping and web mockups and got to say it's a really cool tool, and has allowed me to do really great things in the web arena.
Lately I've been using it to do some prototyping and wireframes for a WPF application I'm currently working on and has fit the bill just ok. There are things that need improvement, that is for sure, but as it's getting better and better is shaping itself as the prototyping tool for anything visual u need.
Due to the DNA I won't be able to post screenshots nor talk about its functionality thought I will try to crawl the web for resources associated to it and make them available as they show up.
The guys over Brand Spanking New have put a good post over some of the new and existing features and the way they work in the new version and how they have evolved from previous versions, go check it.
