bgill,
I honestly think you should see if you can find (or create) different icons for incognito. Love this theme, I just didn't love the icons. Maybe something to add to the to-do
There are 2 apps on the market called FolderOrganizer and BetterCut that will let you change your icons to anything you'd like...there are even icon packs out on these forums in various places. They may help ya.
