AOMPlayer000 - Or rather, Grun - recently contacted me with a mod to the AOEIII editor which improves it greatly:
# You can unlock full camera controls, as in AOM:TT.
# There is no longer fog and black when you quit a testgame.
# There is a small tool that has all protonames of all the units.
# All units can be aligned to the map (if Trading Posts and resources, etc, aren't aligned, then the CPU AI doesn't recognise them.)
# You can pitch many objects by using the keys Ctrl+Up, Ctrl+Down, s, d after clicking move object.
The readme includes details on installation, uninstallation, and some more info. Enjoy.
