I am using Tumbleweed (but the same apply to Leap 42.1) and Plasma 5. The icon
of KDE start menu (application menu) is K instead of Geeko. I did not tested
with KDE 4 or Gnome.
By tradition Geeko was there as part of openSUSE branding.
Please bring Geeko back so it will be easy to identify that we are running
openSUSE and not KDE/Gnome on whatever distro. I just wanted to bring this to
attention in case it was done by accident
and not noticed. Start menu is a good place to put distro logo (other
distro are using it too).

Also, Geeko is missing from Tumleweed wallpaper (it is present in Leap).
