I do some 4-layer and 6-layer boards, where the possibility 
for things to get shorted together multiply,
and it is easy to overlook it when manually checking.  I 
can't say about KiCad as I have not done anything over 2 
layers with it.

EVERYTHING on Protel is configurable, you can add items to 
the menus, create the picture for the menu item, etc.

As for libraries, I really don't trust ANYBODY else's 
library parts, at least until I've checked them.  Protel's 
are actually pretty bad, by the way, so most of them are now 
MY parts, not theirs.
