I think you guys overdid this. While the reporting tool on G+ implies fast reporting: you just select and write a feedback on one page, in less than, say 30 seconds; with Wishbox you have to wait here and there, go from this screen to that and at the end you also spend your time filling the form.
If I actually was to report a feedback with Wishbox, I wouldn't do it because of time consumed.
Please, simplify the process.
