Downloadable Quicktimes would be great and so would .WMV format too
Alas, much as I like what maxwell can do, I rarely use it bar model creation, as it can neither work with my main app as I'd hoped it would when I bought Maxwell in Alpha (I enjoy using Vue much more than Lightwave etc),
nor do I have the time to learn how to work Maxwell Studio properly (by my standards) while I'm learning several other apps at the same time and writing tutorials etc, as well as coping with RL! hehe.
I still haven't seen a good tutorial that gets me ot grips with Maxwell materials, alas. (That's a hint

)
Tell you what would be nice, as I've seen in Vue and some other apps: direct linkage from the HELP menu in Maxwell, to tutorial videos or flash videos, set with an editable directory in prefferences. Now that would be sweet!
Say the help menu has 10 sub sets links, click on them to take you to appropriate video tutorials on that subject, rather than have to hunt for the tutorials.
