Kicker really wants to disable the blend tween completely, because it works very hard \
to reuse existing delegate instances when you switch categories. That is, when you \
move from one category to another and they differ in size, delegates may be created \
or destroyed as needed to fit the new size, but existing ones are reused and just \
handed new data. Since the text labels don't blend it's awkward when the icons do, \
and also generally makes things feel too slow.</p></pre> </blockquote>
