I mostly use KDE programs and just use the Awesome WM as window manager. There the KDE/Qt file dialog works with single clicks everywhere. A single click will enter into directory and also select a file.
A GNOME/GTK file dialog like I get with gnome-boxes or Firefox behaves rather inconsistent. To enter the first directory, I have to double-click, a single-click will only select. Then the next single-click will already enter into the next directory or select the file and close the dialog.
I find this behavior rather upsetting. Is there something I can do about it?
