Version:           4.4 (using KDE 4.4.4) 
OS:                Linux

Filter in file save/open dialog is useless, and unusable to novice/new users who do not know about wild-cards ['*','?'] as:

1. it doesn't filter out the folders, and
2. the user has to manually type *xt*, then press enter to find a file text.txt, text.csv, text.odf etc.. (this slows down and doesn't really make the user productive)
3. user can't filter out a folder
4. user can't 'switch-off' 'switch-on' 'showing folders' when there are many folders, finding files is very difficult.

Reproducible: Didn't try



Expected Results:  
Just like Dolphin's Filter bar, All KDE file save/open dialogs should have same behavior.

Entry in the Bar = expected behavior:
-------------------------------------
[no entry] = * [all files and folders]
*.txt = *.txt [folders and *.txt files]
txt = only files/folder containing txt in it, == *txt*


It would be nice to have "dolphin filemanager kpart" in file open/save dialog. thanks.
