Leading edge stuff like refreshing an entire page when minimizing a content box?

Not sure what you mean there - the only page reload I could find is when changing between the tabs like “Obkject Browser” - what are you referring to with “content box”? Or are you talking about the map?

I’m not blown away. A lot of interface elements are inconsistent (seemingly random list alignment, etc)

On the UI design front I really can’t comment - I’m most impressed by the way they’re putting various technologies together. Perhaps it’s worth bearing in mind the app is still in development and was first “beta’d” end of Dec 2005 but perhaps they could use somem usability expertise?

As far as functionality goes, I could see myself using this - there’s some interesting ideas for how to present a lot of related data to allow fast analysis and comparison by humans. When renting a flat for example, there’s many factors that come into making a choice - what’s the going price for a particular area, availability of public transport, facilities etc., in addition to just finding a flat that matches your basic requirements. From playing around it does help develop and overview very quickly, which is hard to do otherwise.
