You are late. I chewed it up and spit it out already. :-)

Well, I agree my reaction was a little over. So, here is my apology in 
return.

You see, I've seen too many posts hijacked or totally trashed leaving no 
chance to get sometimes much needed help by people just quickly browsing 
an original post instead of really reading it.

Not very often, but I've happened to provide people some help too. 
Certainly there were cases when I genuinely misunderstood a post. However 
I always either read it carefully, or, in case I do not have enough time, 
I either postpone the reading or forget about it.

This is what lead me to overreact. Well, let's close this part for good. 
Agree?

See above. :-)

Yes, you are right. I've already figured it myself, it is Show Desktop 
icon.  And it is supposed to be in the list of widgets, which you open by 
clicking Add Widgets button.

However, after I "smartly" deleted to poor thing, it's gone from the list 
of widgets as well. 

BTW, It just know blinked in my rather old head: could it mean that by 
deleting this widget I actually uninstalled. Though it would be weird 
IMHO. Do you think I can find it in Package Manager and reinstall?

I'm coming from GNOME2 (and trying to escape any forms of GNOME3, Unity 
including) thus I do not know about KDE much yet. So, at times I feel 
quite dumb. :-)
