How to get rid of the Fogger lens?

view full story

http://askubuntu.com – though I prefer using Fogger instead of creating web-apps in chrome, I don't need the Fogger lens in my Unity Dash. The few web-apps I have are easily found via global search or applications lens. I tried sudo apt-get purge unity-lens-fogger and some variations, but had no success. Can anyone tell me under what name the Fogger lens can be removed? Tia Sascha (HowTos)
