Why do you need to retrieve a unique id from the server? That seems 
unnecessarily complicated for what could be done by a QUuid locally, no?

See also my still open questions on your REST API and where to do the 
translation between what KUserFeedback expects to what you have on your 
backend in the  previous discussion with Tino and Tuukka.

What do you want to authenticate with? If this is about using real user 
accounts you are getting close to GDPR territory, no?

I'm fine with changing things, I'm just still trying to understand the 
requirements correctly :)

The audit log features is for users to inspect everything that has been sent 
so far. For the current data that would be sent going forward, see 
FeedbackConfigWidget/FeedbackConfigUiController, that's probably the more 
interesting UI part.
