I fully agree here. I think most likely every user interested as much as
wanting to install this could follow an instruction like "Unpack the
skyculture-XY.zip and put the directory under
<USERDATA>/Stellarium/skycultures", maybe formulated in 1 sentence per OS
to better describe the path name.

Much more interesting are good comets (maybe just 2 growing and rotating
paraboloidal shells for dust and gas tail, coma, arbitrarily shaped
nucleus, and a particle system spewing evaporating gas), satellite shadows
(and given the discussion about dropping OpenGL1 support and the announced
OpenGL2 requirements for Qt5 which is announced for 2012, maybe a
shadowmapping solution with OpenGL2 is enough), meteor streams and maybe
aurorae, the last 2 maybe with some link to online resources with orbital
data for meteor streams, and aurora forecast? Also a moving-cloud plugin
(different cloud shapes, day sky, night sky, light-polluted night,
noctilucent switch?) would be nice.

About non-spherical bodies: we are just developing an OBJ renderer in the
scenery3d branch. OBJ is pretty lightweight and well-known, while Collada
seems very bloated when you just want to add a small irregularly shaped
object. Maybe this code can then be adapted/partially reused for a
StelObject shape. I cannot tell you an exact date of release, yet.

Kind regards,
Georg
