Semantics of SoftFilter:
1. It potentially may match only one side => it MUST NOT be applied while traversing a single folder to avoid mismatches
2. => it is applied after traversing and just marks rows, (NO deletions after comparison are allowed)
3. => not relevant for <Automatic>-mode! ;)
-> SoftFilter is equivalent to a user temporarily (de-)selecting rows
