Yes, is. But that action always uses the program's name in it's display. Which 
is "Konqueror" if embedded in Konqueror :) So KStandardAction::preferences() 
does not work here. You have to create an action on your own.

You could also think about omitting a special "Configure Filelight" entry for 
Konqueror (confuses the user anyway, as they selected "Radial Map" in
"View"->"View Mode" and not "Filelight", so what is this "Filelight") and have 
the config module also embedded within the ones of Konqueror, similar to like 
the Dolphin filesystem views are only configurable there.

Yup, vanished also for me now.

That bigger statusbar even stays once you switch away from the Filelight view. 
Please file a bug for Konqueror if you do not find the reason when digging 
into it.

No, I meant when the mouse moves over the next item which could be selected in 
the filelight view. Currently that one is selected instantly if there is a 
mouse event over the item. That way you have to move your mouse pretty fast 
out of the window so it does not trigger a single event over anything else in 
the view to prevent to have another item selected.
Hm, the menu comparison seems a bad one currently, at least with Oxygen.  
There selection of new items in it is now done also instantly. But I remember 
there is a time-delay possible, to be able to go with the mouse cursor 
directly to lower parts of the submenu just opened, i.e. with passing other 
items of the parent menu for a few milliseconds without having them triggered, 
so the submenu is not switched, to that one of the menu item you only wanted 
to pass.

Got a better idea what I mean?

Please file as bug to them, so they know :)

I guessed this would just fail for any file or dir also named "Used", but 
testing could not confirm this, okay. Ah, the "if (m_summary){" explains this.
A comment about that would not be too bad for your fellow coder looking into 
that code and wondering as well :)

If you like, okay. Removing the root of evil still preferred if possible. ;)

Yes, looks like problem elsewhere.

Please also help out with
as Alexander requested, some i18nc with proper comment should do.

The minimum-height-bigger-than-my-screen-resolution seems a problem only 
experienced by Albert so far, so I consider that something to be solvable 
after the move.

Given that Albert and Burkhard both had a look but did not complain about any 
further translation/documentation problem I also see no blocker in that, 
unless they object now :)

So please improve that unclear message as indicated by Alexander, and then I 
would like to have filelight move into kdeutils.

Will you do the move yourself, or do you want me to do that?

Will add a section on for it, or do you plan to keep the 
old/current homepage for it? Max Howell still involved in filelight?
