If rows are moved in the source, the proxy handles that itself. The proxy 
will do a layoutChange, which is similar to a full reset. QML treats a 
layoutChange as a full reset.

Right. But QSortFilterProxyModel never emits rowsMoved, even if you use it 
in your source model. QSortFilterProxyModel treats that as a layoutChange.

All the best,
