Singleton cache to lookup?
Like QHash<QString, DirSettings>

class DirSettings {
   QDateTime timeStamp;
   bool showHidden;
   Foo bar;
   ....
};


Would work for at least single process cases.
(Though dolphin is no more KUniqeApplication? Spawns new processes instead of windows here)

I'll try a naive and risky "moveToThread()" tonight ;-)
