I think that MaxIDE could have a few little changes that would make alot more difference in how it looks. These would only work on the Windows version (the manifest atleast).
Have the Editor font 'Courier New' instead of 'Courier'.
The Output and Navbar should be 'Verdana' 8pt.
MaxIDE should have a manifest, or a proper resource file when compiled.
Here's what it could look like:

IMHO those changes make it look way nicer than its default look.
Note: The code's MiniB3D, not mine.
