I’m excited to announce that Config Tool has now been approved for the App store and v1.0.0.1 is available to install now!
Check it out: http://office.microsoft.com/en-au/store/config-tool-WA104165158.aspx
The trial version of Config Tool supports a limited set of functionality (5 custom fields imported at most), but should give you a good feel for the tool.
Either way if you like Config Tool then rate it and feel free to leave some feedback here or in the Support page.
