And lastly, Konqueror didnt save it window state (size,minimize/maximize). How do it?
For a default
Window state in File management "mode" simply
Save view profile file management
Save window size in profile (click the tick box at bottom of dialogue)
Save as filemanagement (ie just save-over same name)
each directory you now open in file management mode will have those chosen settings.
To customise the Window state for any single
Click on - View properties saved in directory
make your Window state changes
Click off - View properties saved in directory
each time you open that directory it will be exactly as you set up.
