I was using Fireworks software for long time, mostly testing into detail and Fireworks CS5 is top of the line product.
Mac people can now be happy it works excellent.
Of course there is always room for upgrades, and not be so much positive let me find at least 1 thing that could be better and then we could say Fireworks CS5 would be perfect.
Have for example panels, see Path panel that one looks perfect, but why other panels didn't follow that same design flow ? now thats a shame, when you know you can do it all to be great... but you don't do it
Please make panels to be more consistant to each other, look at the Path panel this is perfection seen so far.
