Hello, Mathias!
I think there is a bug in importing settings. I can't import settings except those located on the first tab. It is easy to reproduce. You need to export either Core or Explorer Panel settings. Then you need to import them immediately. There are neither checkboxes nor folding markers apart from first-tab settings ones, but there are correspoing tags in xml file. I've attached a screenshot. My version is 4.6.2 64bit.
