Hello pingber, I am a LG user like you. You have a C1 and I have a C3. Netherless, the home screen should look like the attached picture of my home screen (sorry it is in french). The last row contains input and some documentations in my case. If this is also your case, then for this last (bottom) row you cannot change it. Witht the lastest WebOS version, you cannot remove the different rows. Unfortunately, WebOS is quite rigide : and you cannot really customize and simplify the home screen. Phil.
