I came across Constellation Roamer a few days ago, and was impressed with what Daniel Mclaren had produced. His responsiveness since then has been great, he immediately addressed some of the minor points in my review, like the missing price on the site and expanded documentation. Now he’s released a new version with a lot of extra features. The Javascript support he offers could be very useful for some of my work, it will allow the display of extra information in the main page whenever the user selects a node for example.
It’s great to see him offering this Flash component, and the level of service he’s shown so far makes me very confident you’ll get strong support from him after the purchase. I’m looking forward to using it myself, and I’m sure it will be useful for a lot of other sites too.
