Is your Opera running while cleaning?
I asked this question as I follow your discussion on the matter here and on other forums too and you were saying that some features are extra for the donors but I never found them mentioned anywhere.
1. The Donors version is "Donate what you want, when you want" as described here :
2. The free version is gratis.
3. if you want additional features, donate and get the Donors version.
4. Yes as shown here. There is a section "registry".
But some users don't want to clean the registry, so we added a checkbox (see on the bottom-left) to make sure even internet traces that can be found in the registry are not cleaned.
