Hi all, after installing some apps i have a dummy icon in my N9 applications launcher, it doesn't do anything, so i want to delete it, but, i was unable do find the item's .desktop file,

So i was thinking if there is some sort of applications launcher configuration for items order, allowing me to determine the file to delete.

Does anyone knows if these exists, and where? Or any other idea?

Sorry for opening a new thread for such a dumb question, but i can't find these any where.

Thanks.
