[Michal Karnicki <michal.karnicki@xxxxxxxxxxxxx>]

I agree with what Michael said. Qt labs settings turned out to be a very
simple drop-in solution for some basic setting storage we required in an
app that we're developing. I had a look at the comparison document, and I
also agree that the upstream implementation seems much simpler/more
compact. I do not have much experience with U1Db, so I can't express
opinion on that end, but I found Qt labs settings to be simple and
convenient way to store (at least basic) settings.

I also like the idea that mhall suggested regarding wrapping the upstream
component (if that would be feasible).

Thanks,
karni
