Yes, and yes - could be an i18n issue  - but that is sth. translators have  
to deal with all the time (eg. short strings can become considerably long  
in other languages)

The better avoid them =)

[ ] Only use windows that are ( ) Minimized
                                                      ( ) not minimized

[ ] Only use windows on          ( ) this Desktop
                                                      ( ) other Desktops

Takes however more space.

Me neither, I attached Stefano (i don't think he's subscribed to kwin@kde)

@Stefano:
There's currently a question why the multiscreen option is ternary, ie.  
you can select
* on this screen
* on other screens <- this is the questioned setting
* on all screen

Can you please elaborate on the rational behind?

Shannon entropy, yes. Nothing directly to do with thermodynamics (directly)
see here:
http://en.wikipedia.org/wiki/Entropy_(information_theory)#Relationship_to_thermodynamic_entropy
and also the following paragraph which links there:
http://en.wikipedia.org/wiki/Shannon's_source_coding_theorem

Actually it matches, because a disordered system cannot be compressed w/o  
information loss.
It's confusing nevertheless and i though <thought  
class="imprudent">Americans should perhaps stop abusing artificial terms  
they probably don't understand just to appear smarter than they  
are</thought>
(though to be fair, translating thermodynamic entropy to "disorder" is  
simplifying and actually "information density" doesn't really cut it  
either, one could however just have made up another word - *shrug* ;-)

Is "information density" a common English term?
