New feature is Debugger panel. Right now it has one tool called unSerialize. It’s very simple, and allows you to paste any serialized PHP string and you will get unserialized visualization of it. Display can be done using standard print_r or advanced gdp_r function (also GD Press Tools Pro exclusive).
On the image on the right you can see result of the process. Top part is the original serialized string, and on the bottom is gdp_r visualized result of the serialized object.
