[bonega]

Public bug report changed:

Description changed to:
    The home icon is not obvious thanks to poor visibility.
    In 24x24 the house is 8pixel wide and very hard to identify, 16x16 is even worse.
    Classical solution is designing a houseshaped folder.

    All harddrive icons are way too thin and feels like wrong
    perspective compared to other icons.

    Places->Networkservers is too crowded, I suggest removing the
    computer from it.
