and I only answered to that.

ok. I cannot give you usability studies, because they don't exist. But you can 
try it yourself. Just use it! Just try this setting for a day or two. Give it 
to a non-experienced user.

Of course it has to do with technical aspects of the window manager. You can 
only choose a default if you understand it. If you understand every detail of 
it. If you know and understand the underlying code and the history behind it.

If you just had looked into the code, if you had tracked down why it is the 
default, you would not even have come up with the proposal.

Just to give you an idea. The placement policy centered was not always called 
centered. It was committed as "StupidlyCentered". It did not even had a GUI 
option, because it is so stupid. It is from 2002 and has not changed at all, 
the code is still the same (except an internal adjustment).

Seriously? Do you want to use that as the default?

The usability study for placement policy smart might be that it was used in 
KWM and based on code from an even older window manager. Maybe 15 years of 
experience in good window placement are an argument, maybe not.

You can spend your time on discussing each config option of KDE which have not 
changed in the last 12 years. All is fine with that. But I can only recommend 
you to concentrate on what is important. The KDE devs are not all stupid and 
for most of the defaults there are good reasons.

And even if you come up with a new default I can only suggest that you go 
afterwards to the maintainers of the specific KDE application and ask why they 
had the default and not the one you use. There might be very good reasons to 
not use your default. Remember: you did not develop the applications, you 
don't know the limitations!

In this case here the maintainer of the specific application tells you even 
before that it is a bad idea to change the default.

Kind Regards
