I am trying to uncover anything useful from my corrupted Chrome profile (as Chrome doesn't sync a lot of things, like extensions local data, etc.) and I'm not sure what I should or should not copy.

I see that you also did a good research on the matter. If you don't mind I'll try to contact you via comments sometime in the future if I'll continue my project.
