thanks for the explanation, that really helps me in deciding whether or not to use shapeshifter (which i really would like to do!)

speaking of slowing down the system, would shapeshifter cause my system to slow down at all? even in the slightest bit? for example, being cpu intensive or hogging lots of memory. one major reason, besides the risk of damaging my system, to not use shapeshifter is slowing down performance of my computer. will this happen at all? this question goes for any unsanity apps like windowshade, silk, labels x, or the cleardock app as well

also, about themepark, does this do the same thing as shapeshifter? if not, could i be using both themepark and shapeshifter in conjunction? would this present any conflicts?

and about candybar, any risks involved with using that app? im assuming no but i'd just like to make sure if anyone knows for sure.

ps. what is APE?
