Nice to see that both projects are nicely going along =)

I think I was the one who mentioned it, but I'm not sure because it was a
long time ago, already ;) so no offense if you refered to someone else :)

I would be glad to have a global detail level for all object, set to a
default value stored in the preferences. To another level, the user should
be able to override the default value for a particular object with a lower
or higher value. For instance, when manually placing objects on the top
surface of a height field, since there's no openGL shading yet, the
highest level of detail is required to set the altitude coordinate of the
object to be placed. Once all placement are done, the lowest level of
detail is then needed (if needed at all) as I usually concentrate on other
parts of the scene.

So my example workflow would be (from a range from 0 to 5, for example) to
set the LOD of the HF to 5, place my objects along the surface, turn the
LOD to the default 1 or 2 I like most, then select an other object, set it
to 4 because I will model another object around it, then turn it back to
the default 1 or 2, and so forth...

Hope my explanations make sense ;)
