MetaCard tab buttons have a seemingly minor but rather significant 
usability issue:  the label for the selected tab is almost 
indistinguishable from the other, non-selected tabs.  Yes, the tab size 
is increased a couple pixels, but this is the only visual change, and in 
a light-colored layout this change is not clear enough, or at least as 
clear as other, more conventional tab drawing methods (see the Mac HIG 
for good tab examples - 
<http://developer.apple.com/techpubs/mac/HIGOS8Guide/thig-29.html#HEADING29
-0>).

Ideally, there would be a new property for tab controls which allows us 
to define the unselectedColor, the color of those tabs behind the current 
one.

In absence of this, what do you folks do?  I've hard-wired all manner of 
solutions in the past, but at the moment I have a particularly tough case 
in which the tab labels must be dynamic, which prevents me from using any 
hard-wired additional objects, and makes setting the location for other 
objects problematic (cross-platform font widths are hard to predict).

Any tips would be much appreciated -
