Yup! Found out the pros to have icon support after entering safe mode a few times
Actually, icon support screws up the way iTunes reads your layout

. That's why my initial thoughts was "hey, this is pretty cool"
Because by default, your device uses the IconState.plist, but when iconsupport is installed, your device makes a new file called IconSupportState.plist and uses that
And any change you make to your springboard layout will make changes to IconSupportState.plist, and not IconState.plist
iTunes reads the IconState.plist, so that's why the two layouts can differ (iTunes app pages vs your phone's actual pages)
And yes, agree super helpful if you enter safe mode. Let's say folder enhancer in iOS 6.x. All the "extra icons" in the folder will be thrown out and you'll be left to manually fix them when you enter normal mode from safe mode (unless you backed up file and just replace it afterwards)
