Frederico,
I did try it. I used the highlighter on a custom item renderer. looks good on
initial display but when you try scrolling the list component, the display
screws up. the rectangular "box" used as background doesnt "flow" with the
text. something to do with relative x,y positioning. looks like it was not
designed to be used for renderers.
