      (LP: #814574)
    - Unity launcher gets cluttered when having multiple partitions and/or
      external volumes attached (LP: #713423)
    - Unity panel menus and indicators slow to respond. Too much lag.
      (LP: #742664)
    - In Unity the distinction between GVolume, GDrive and GMount is a bit
      confusing. (LP: #799890)
    - Launcher - When a item is deleted by dragging to Trash, the trash should
      pulse once before the Launcher disappears (LP: #750311)
    - ccsm needs an option to change launcher opacity (LP: #815032)
    - add a ccsm option to hide volumes in launcher (LP: #794707)

  * distro-patch the grey to darker grey (until the blur is done in nux)
  * Switch to dpkg-source 3.0 (quilt) format
  * debian/patches/01_revert_removed_function_for_unity2d_to_build.patch:
    - revert a removed API making unity-2d not building
