I apologize for the delay. I have not been paying attention to this mailing
list for the past couple of months. My responses are below.

That sounds like a decent feature request. Could you please file one at
either sourceforge or github?

This is more of an issue regarding colormap norms. You might want to read
up on them here:

Not currently. These are hard-coded. I am hoping to have that and other
things configurable in the next release of mpl.

Are you talking about the ticks, or the labels for the tick locations? Note
that in 2d plots you can have ticks without labels, or labels without
ticks. Currently in mplot3d, this is not very neat, and it is one thing I
want to have cleaned up for the next release.
