file-picker-dialog

kate uses kde5 file-picker-dialog

You should install oxygen icon pack:

sudo apt-get install oxygen-icon-theme*

and if the left side panel (file list..) is missing:

sudo apt-get install kdelibs-bin kdelibs5-data kdelibs5-plugins

"Kate uses QT file dialog not KDE's"

The only workaround I've found is to use Konqueror to browse the filesystem, and then use the right-click context menu to open the file with Kate.

Note that installing Kubuntu-desktop and/or Plasma instead of Unity does NOT fix the problem with Kate.

The file chooser and save as dialogues are related to the graphical toolkit upon which an application is built, and in no way related to default file manager. Since most programs use gtk toolkit under Ubuntu, I see no possible way of altering those dialogues. There's possibility of switching to Qt-based desktops, but at least in my experience under razorqt that didn't do the trick. Therefore my answer to this question is altering file dialogues is impossible. There's other, more experienced users that me, hence perhaps there might be other answer, so my answer isn't conclusive
