irrelevant. problems should be addressed if they can without inflicting damage 
on other aspects of the UI. small problems need fixing as much as big 
problems.

every component should reflect its own state. this is why buttons show whether 
they are default, have focus or are disabled, for example. whether you have 2 
buttons or 100. the number is irrelevant. reflecting state is vital.

the harm done is that you can't tell just by looking at it. instead you have 
to aim your mouse (or use the keyboard controls) to try and move down more 
and then decide whether or not things moved. in other words, there is MORE 
thinking required, not less, on the part of the user.

this is a style issue AFAIK and should be taken into consideration in keramik 
IMO.
