I already gave examples: kdevelop, kate, kile. Non-kde: openoffice.

Exactly. So there is cost.

(I beg to differ that launched app has no impact on CPU at all).

I didn't notice that because of such heavy load on my computer that I 
had to add switches before running any app to check if there is 
enough ram. Running amule + virtualbox + some computation stuff is a 
guarantee (at least for me) to have frozen computer. 2GB RAM.

KDE has enough problems with running applications at the same time 
(like I am unable to scroll mail in KMail because Konqueror does 
something) already (2GHz CPU).

However, this is going in wrong direction in general -- you would like 
(?) to just add more complexity to flawed design. Making whole 
architecture more complex, more error-prone will not hide the fact 
that the underlying source of those changes has flaws anyway.

Problem of relaunching application is just _one_ of the reasons why 
suggested UI should be rejected (and it is). Not the only one reason.

Cheers,
