gtk 3.14 file chooser: folders first

I just upgraded from fedora20 to fedora21 and now the gtk file picker sorts files and folders together. I much prefer the usual and previous behaviour of displaying folders first (and I enabled that behaviour in nautilus thanks to the option there).

Is it possible to achieve that sorting also in the gtk 3.14 file chooser? If yes, how?


Ok, I found it... I had to install and run the program dconf-editor. Then go to org->gtk->settings->file-chooser, then activate the option sort-directories-first.
