I think that a singleton object (maybe in KIO) that can be used to manage the Places might make sense. \
This could make it possible to find out if a URL is in the Places without expensive Solid queries for the \
devices, and it would also make the code in Dolphin's PlacesItemModel and KFilePlacesModel easier. I have \
been thinking about this for quite some time, but have not managed to work on it yet.
